Description

Die Erfindung betrifft einen Gleitkörper, insbesondere einen Ski oder eine Gleitkufe, wie sie bei Geräten und Fahrzeugen verwendbar sind, insbesondere für Schnee- Eis- aber auch Wassersport.The invention relates to a sliding body, in particular one Skis or a skid like those used in equipment and vehicles can be used, especially for snow, ice, but also Water sports.

Wesentlich für die Gleitfreundlichkeit sowie für die Richtungsstabilität bzw. für die Lenkbarkeit oder Manövrierbarkeit und auch für die Haltbarkeit gegen stossartige und schwingende Belastungen ist das Schwingungsverhalten des Körpers bzw. seiner mit dem Gleitmedium in Wechselwirkung tretenden Aussenteile. Gemäss üblicher Technik wird dabei im wesentlichen nur auf das Schwingungsverhalten in sehr niedrigen Frequenzbereichen Bedacht genommen.Essential for the ease of sliding and for the directional stability or for steerability or maneuverability and also for durability against shock and vibrating loads is the vibration behavior of the body or its with the External parts interacting with the lubricant. According to Conventional technology is essentially only based on the vibration behavior in very low frequency ranges taken.

So sind aus den Schriften FR-A-2 643 431 und DE-U-93 16 692 Gleitkörper mit äquidistanten Folgen von gegeneinander abgegrenzten Bereichen bestimmter Flächen-Massendichte, Biege-Verformungssteifheit oder Dämpfung bekannt. Damit lassen sich allenfalls grossräumige bzw. makroskopische und niederfrequente Schwingungseffekte beeinflussen, jedoch bestehen nach wie vor wesentliche Verbesserungsbedürfnisse hinsichtlich der Schwingungseigenschaften von Gleitkörpern.So are from the documents FR-A-2 643 431 and DE-U-93 16 692 Sliding bodies with equidistant sequences of delimited from each other Areas of certain mass per unit area, bending stiffness or damping known. With that you can at most large-scale or macroscopic and low-frequency Affect vibration effects, but still exist essential improvement needs with regard to the vibration properties of sliding bodies.

Aufgabe der Erfindung ist daher die Schaffung von hinsichtlich der vorgenannten Gesichtspunkte weiter verbesserten Gleitkörpern. Insbesondere sollen dabei die mittleren und höheren Frequenzbereiche bzw. Eigenschwingungsfrequenzen und vor allem das Resonanzspektrum in diesen Bereichen Berücksichtigung finden. The object of the invention is therefore to create in terms of the aforementioned aspects further improved sliding bodies. In particular, the middle and higher frequency ranges or natural vibration frequencies and above all that Find resonance spectrum in these areas.

Die erfindungsgemässe Lösung der gestellten Aufgabe ist bestimmt durch die Merkmale der Patentansprüche 1 bzw. 2. Die Merkmale der abhängigen Ansprüche verkörpern wesentliche Weiterbildungen der erfindungsgemässen Lehre, die insbesondere auch in verschiedenen anspruchsgemäβen Kombinationen anwendbar sind.The inventive solution to the problem is determined by the features of claims 1 and 2. The features of the dependent claims embody essential developments the teaching according to the invention, in particular also in various Combinations according to the requirements are applicable.

Der Grundgedanke der Erfindung besteht also in der Verwirklichung wenigstens einer schwingungsaktiven Gliederung mit Mehrfach-Eigenfrequenzen durch mindestens eine Reihe aus aufeinanderfolgenden Raum- oder Flächenbereichen, deren Schwingungsparameter in der jeweiligen Folgerichtung progressiv oder degressiv variant bemessen sind. Dabei können die Schwingungsparameter in Form von gegenseitigen Abständen vorgegebener Abschnitte innerhalb der aufeinanderfolgenden Bereiche oder auch in Form der örtlichen Massendichte, Biege-Verformungssteifheit oder Dämpfung innerhalb der aufeinanderfolgenden Bereiche vorliegen.The basic idea of the invention is therefore the realization with at least one vibration-active structure Multiple natural frequencies from at least one row successive spatial or surface areas whose Vibration parameters progressively in the respective subsequent direction or degressive variant. The vibration parameters specified in the form of mutual distances Sections within the successive areas or also in the form of the local mass density, bending deformation stiffness or damping within the successive Areas.

Im Folgenden werden die Raum- bzw. Flächenbereiche mit in ihrer Aufeinanderfolge varianten Schwingungsparametern kurz "ausgezeichnete Bereiche" genannt.In the following, the room or surface areas with in their sequence of short vibration parameters called "excellent areas".

Zur gemeinsamen Grundlage der Erfindungsvarianten sei noch folgender Hinweis gegeben: Schwingungsaktiv im Sinne der Erfindung ist eine Gleiderung, deren in mindestens einer Reihe aufeinanderfolgend, insbesondere in gegenseitiger Koppelung angeordnete ausgezeichnete bzw. von ihrer Umgebung differenzierte Bereiche hinsichtlich ihrer eigenen Schwingungsparameter bzw. hinsichtlich der durch Koppelung mit ihrer Umgebung gegebenen Schwingungsparameter im Bereich von Eigenfrequenzen oder des des als Ausgangsobjekt gegebenen oder des mit bestimmten Eigenschaften zu verwirklichenden Körpers liegen. Eine quantitative Abgrenzung der Schwingungsaktivität muss sich daher nach den Gegebenheiten des jeweiligen Anwendungsfalles richten. Diese Abgrenzung ist aufgrund an sich bekannter Kriterien theoretisch bzw. rechnerisch oder experimentell ermittelbar, oft sogar unmittelbar evident. Die Wirkung einer solchen schwingungsaktiven Gliederung richtet sich demgemäss auf eine angestrebte Gestaltung des Eigenfrequenzspektrums. Ziel kann sein z.B. eine Verdichtung der Eigenfrequenzen, d.h. eine Erhöhung der Anzahl von Eigenfrequenzen in einem gegebenen Frequenzbereich, bzw. die Schaffung neuer Eigenfrequenzen wie auch eine Vergleichmässigung, Überhöhung oder Absenkung des Verlaufes der Resonanzamplituden in einem Frequenzbereich oder mehrerer derselben. All dies kann für eine gezielte Beeinflussung von Gleitkörpern hinsichtlich ihrer Gleit- und Laufeigenschaften und/oder ihrer Lenkbarkeit bzw. Manövrierbarkeit, aber auch ihrer Haltbarkeit gegenüber dynamischen Beanspruchungen eingesetzt werden.The common basis of the variants of the invention is still the following note is given: vibration active in the sense of Invention is an outline whose in at least one row successively, especially in mutual coupling arranged excellent or differentiated from their surroundings Areas in terms of their own vibration parameters or in terms of that is given by coupling with their environment Vibration parameters in the range of natural frequencies or the the one given as the starting object or the one with certain Characteristics of the body to be realized. A quantitative one Delimitation of the vibration activity must therefore be the circumstances of the respective application. This delimitation is theoretical based on criteria known per se or can be determined mathematically or experimentally, often even immediately evident. The effect of such a vibration active Outline is accordingly aimed at a desired Design of the natural frequency spectrum. Target can be e.g. a Compression of the natural frequencies, i.e. an increase in the number of natural frequencies in a given frequency range, or the creation of new natural frequencies as well as an equalization, Increase or decrease the course of the Resonance amplitudes in one frequency range or more the same. All of this can be used for targeted influencing Sliders in terms of their sliding and running properties and / or their maneuverability or maneuverability, but also their durability against dynamic loads be used.

Vielfach, insbesondere z.B. für Skier und Gleitkufen, grundsätzlich aber auch für in Medien bewegte Trag- und Auftriebskörper wie Bootsrümpfe und dergl., wird eine Verminderung der Oberflächenreibung angestrebt. Dazu kann eine Verstärkung oder Neuschaffung von relativ hohen Eigenfrequenzen im Oberflächenbereich des Körpers dienen.Often, especially e.g. for skis and skids, basically but also for support and buoyancy bodies moving in the media such as Boat hulls and the like will reduce the surface friction sought. This can be a reinforcement or new creation of relatively high natural frequencies in the surface area of the Body.

Andererseits unterliegen Gleitkörper im Betrieb im allgemeinen einer ständigen, jedoch unregelmässigen, d.h. durchweg nicht periodischen, Beaufschlagung mit mehr oder weniger stossartigen Druckkräften und/oder Biege- und/oder Torsionsmomenten. Dadurch wird eine entsprechend unregelmässige Folge von mit den Eigenfrequenzen des Körpers angeregt. Entsprechende elastische Verformungen haben meist vor allem in tieferen Frequenzbereichen unerwünschte Wirkungen, sind aber gerade in diesen Frequenzbereichen relativ schwierig zu dämpfen. Eine Verlagerung der Eigenfrequenzen in höhere Frequenzbereiche oder eine Erhöhung der Resonanzamplituden in diesen Bereichen mittels geeignet ausgelegter, schwingungsaktiver Gliederungen kann hier Abhilfe schaffen, und zwar oft mit relativ geringem Bauaufwand. Insbesondere ist festzuhalten, dass die Anregungsenergie seitens der aufeinanderfolgenden, stossartigen Beanspruchungen in einer gewissen Verteilung auf die Eigenfrequenzen des Körpers aufgenommen wird. Eine relativ grosse Anzahl von Eigenfrequenzen bzw. eine erhöhte Eigenfrequenzdichte, wie sie durch Anwendung der Erfindungsmerkmale einfach erreichbar ist, kann demgemäss für eine generelle Verminderung der maximal auftretenden Schwingungs- bzw. Verformungsamplituden genutzt werden, bevorzugt in Verbindung mit einer Verlagerung der Schwingungsenergie in relativ wenig störende Frequenzbereiche.On the other hand, sliding bodies are generally subject to wear during operation a permanent but irregular, i.e. consistently not periodic, exposure to more or less jerky Compressive forces and / or bending and / or torsional moments. This results in a correspondingly irregular sequence of stimulated with the natural frequencies of the body. Appropriate elastic deformations mostly have deeper ones Frequency ranges have undesirable effects, but are currently in to dampen these frequency ranges relatively difficult. A Shifting the natural frequencies to higher frequency ranges or an increase in the resonance amplitudes in these areas suitably designed, vibration-active structures can be found here To remedy this, often with relatively little construction work. In particular, it should be noted that the excitation energy on the part of the successive, sudden loads in one certain distribution on the natural frequencies of the body becomes. A relatively large number of natural frequencies or an increased natural frequency density, as can be seen by using the Features of the invention can be easily reached, accordingly for a general reduction in the maximum vibration or deformation amplitudes are used, preferably in Connection with a shift of the vibrational energy in relatively little disruptive frequency ranges.

Vorteilhaft wird dabei wenigstens eine Aufeinanderfolge mit einer Vielzahl von ausgezeichneten Bereichen, insbesondere mit mindestens 5 solcher Bereiche, vorgesehen. Ein wichtiges Merkmal besteht ferner darin, dass mindestens eine oszillierend variante Reihe von ausgezeichneten Bereichen mit vorgesehen ist. Insbesondere kommen auch Gliederungen mit sich in unterschiedliche Raum-oder Flächenrichtungen erstreckenden Reihen von ausgezeichneten Bereichen in Betracht. Die Gliederungen mit ihren Reihen von ausgezeichneten Bereichen können in wenigstens einem Oberflächenabschnitt und/oder wenigstens einem Wandungsabschnitt eines Hohlraumes des Gleitkörpers bzw. längs wenigstens einer Kante eines Gleitkörpers verteilt angeordnet sein. At least one sequence with is advantageous a variety of excellent areas, especially with at least 5 such areas. An important feature further consists in that at least one oscillating variant row of excellent areas. In particular also come with different room or structure Area-extending rows of excellent Areas into consideration. The outlines with their rows of marked areas can be in at least one surface section and / or at least one wall section a cavity of the sliding body or along at least one Edge of a sliding body can be arranged distributed.

Ein weiterführender Erfindungsgedanke ist gekennzeichnet durch mindestens eine schwingungsaktiv gegliederte Oberflächenschicht bzw. mindestens einen Schichtabschnitt, insbesondere in Form einer Granulat-, Lack- und/oder Folienbeschichtung, vorzugsweise mit Metallgehalt.A further inventive idea is characterized by at least one vibrationally structured surface layer or at least one layer section, in particular in the form of a Granulate, lacquer and / or film coating, preferably with Metal content.

Die ausgezeichneten Bereiche können - vor allem hinsichtlich ihrer Abmessungen - bestimmt sein durch Unterschiede ihrer Schwingungsparameter in Bezug auf die Bereichsumgebung innerhalb des Gleitkörpers. So können die Verformungssteifheit, die Masse oder in Massendichte bzw. die Dämpfung innerhalb eines ausgezeichneten Bereichs in Bezug auf dessen Umgebung höhere oder auch niedrigere Werte aufweisen. Dies kann in technisch einfacher Weise mittels in einen umgebenden Grundkörper eingebetten oder in sonst geeigneter Weise mit diesem verbundenen, hinsichtlich Material und/oder Abmessungen gegenüber dem umgebenden Grundkörper kontrastierenden Elementen bzw. auch mittels Aussparungen oder Einsenkungen, insbesondere z.B. in Form von Kalotten oder Kerben erreicht werden.The excellent areas can - especially with regard to their Dimensions - be determined by differences in their vibration parameters in terms of the area environment within the Sliding body. So the stiffness, the mass or in mass density or the damping within an excellent Area in terms of its surroundings higher or also have lower values. This can be done in a technically simple manner embedded in a surrounding body or in another suitably associated with this, in terms of material and / or dimensions compared to the surrounding base body contrasting elements or by means of cutouts or Depressions, in particular e.g. in the form of domes or notches can be achieved.

Eingehende Untersuchungen und praktische Versuche haben gezeigt, dass die Abstands- und/oder Unterteilungs- und/oder Wertefolge wenigstens annähernd entsprechend einer harmo- nischen, in besonderen Fällen gegebenenfalls entsprechend einer geometrischen Reihe zu bemessen ist.In-depth investigations and practical tests have shown that the distance and / or subdivision and / or sequence of values at least approximately according to a harmonic, in special cases, possibly according to a geometric Row is dimensioned.

Eine sprunghafte Weiterbildung der Erfindungsgedanken besteht darin, wenigstens eine schwingungsaktive Gliederung vorzusehen, die mindestens eine sich linienförmig, flächenhaft oder räumlich erstreckende Ueberlagerungsstruktur aus wenigstens zwei Abstands-und/oder Unterteilungs- und/oder Wertereihen enthält. Dabei kann in spezieller Ausformung dieses Merkmals wenigstens eine schwingungsaktive Gliederung mit mindestens einer sich linienförmig, flächenhaft oder räumlich erstreckenden Ueberlagerungsstruktur vorgesehen werden, die wenigstens zwei Aequidistanzreihe enthält.A leap forward development of the inventive ideas exists in providing at least one vibration-active structure, the at least one is linear, flat or spatial extending overlay structure consisting of at least two spacing and / or Subdivision and / or value series contains. It can in a special form of this feature at least one vibration-active Outline with at least one linear, areal or spatial overlay structure be provided, which contains at least two equidistance series.

Die Werte und/oder Verteilung mindestens eines Schwingungsparameters in den aufeinanderfolgenden ausgezeichneten Bereichen jeweils einer Reihe, z.B. innerhalb jeweils einer Aequidistanzreihe, können wiederum wenigstens annähernd gleich bemessen sein, vorzugsweise werden diese Werte jedoch wenigstens abschnittsweise entsprechend mindestens einer harmonischen oder mindestens einer geometrischen Reihe oder entsprechend einer Ueberlagerung solcher Reihen bemessen. Reihen der letztgenannten Art haben auch in nicht überlagerten Gliederungen vielfach besondere Vorteile bewiesen.The values and / or distribution of at least one vibration parameter in the successive excellent areas one row at a time, e.g. within each equidistance row, can in turn be dimensioned at least approximately the same, however, these values are preferably at least in sections correspondingly at least one harmonic or at least one geometric series or according to an overlay of such Dimension rows. Rows of the latter type also have no in overlaid outlines have often proven special advantages.

Besonders eingehend sind die Erfindungsmerkmale an Skiern bzw. Gleitkufen untersucht und optimiert worden. Dabei hat es sich als wesentlich erwiesen, dass wenigstens eine schwingungsaktive Gliederung mit mindestens einer sich in Längs- bzw. Laufrichtung des Ski- oder Kufenkörpers erstreckenden Aufeinanderfolge von ausgezeichnet Raum- und/oder Flächen- und/oder Linienbereichen mit jeweils mindestens einem in Bezug auf wenigstens einen Nach-barbereich oder innerhalb eines Bereiches selbst unterschiedlich bemessenen bzw. verteilten Schwingungsparameter verwirklicht ist.The features of the invention on skis or Skids have been examined and optimized. It turned out to be proved essentially that at least one vibration-active Outline with at least one in the longitudinal or running direction of the ski or skid body extending sequence of excellent spatial and / or area and / or line areas each with at least one in relation to at least one neighboring area or different within an area itself dimensioned or distributed vibration parameters is realized.

Die Erfindung wird weiter anhand von in den Zeichnungen schematisch dargestellten Ausführungsbeispielen erläutert.The invention is further illustrated in the drawings schematically illustrated embodiments.

Neben seiner statischen Tragfunktion zur Verstärkung des Gleitkörpers hat dieses Element als Bestandteil des Gesamtkörpers wesentlichen Einfluss auf das Resonanzspektrum und das Einschwingverhalten. Speziell ist hier eine über die Balkenlänge ungleichförmig verteilte Gliederung G des Längsprofils vorgesehen, die aus einer hinsichtlich der Profilhöhe additiven Ueberlagerung von vier äquidistanten Reihen R1 bis R4 besteht. Jede dieser Reihen umfasst ausgezeicchnete Bereiche A1 bzw. A2 bzw. A3 bzw. A4 erhöhter Biege-Verformungssteifheit sowie mit letzteren alternierend angeordnete ausgezeichnete Bereiche B1 bzw. B2 usw. verminderter Biege-Verformungssteifheit. In den versteiften Bereichen liegt wegen des grösseren Balkenquerschnitts auch eine grössere Massenbelegung vor, sofern nicht durch zusätzliche Massnahmen - etwa eine Verminderung der Profilbreite oder eine Verminderung der Querschnittsfläche im mittleren Bereich der Querschnittshöhe, z.B. in Form von Aussparungen oder Durchbrechungen - eine Kompensation oder sogar Ueberkompensation dieser Massenvergrösserung vorgenommen wird.In Fig. 1 is a thrust resistant with a sliding body wall RB connected stiffening rib in the form of an elongated Vibrating element SE indicated. In addition to its static support function to reinforce the slider has this element as Part of the whole body significantly affects that Resonance spectrum and the transient response. Special is here an unevenly distributed structure G des over the length of the bar Longitudinal profile provided from a profile height additive superposition of four equidistant rows R1 to R4 consists. Each of these rows includes excellent areas A1 or A2 or A3 or A4 with increased bending deformation stiffness as well as excellent areas arranged alternately with the latter B1 or B2, etc. reduced bending deformation stiffness. In the stiffened areas are due to the larger beam cross-section also a larger mass allocation before, if not by additional measures - such as reducing the profile width or a reduction in the cross-sectional area in the middle Section height range, e.g. in the form of recesses or Breakthroughs - compensation or even overcompensation this increase in mass is made.

Das Schwingungsbild eines Resonanzkörpers besteht im allgemeinen aus einer vielfältigen Ueberlagerung von stehenden Wellen unterschiedlicher Wellenlänge und Amplitude. In den Knotenbereichen herrscht dabei eine geringe bzw. verschwindende, in den Bauchbereichen eine maximale, elastische Biegeverformung. In den Bereichen erhöhter bzw. verminderter Biegesteifheit wird infolgedessen die Ausbildung von Schwingungsknoten bzw. Schwingungsbäuchen begünstigt. Während nun eine einfache, äquidistante Verteilung von Bereichen erhöhter und verminderter Steifheit die Ausbildung einer stehenden Welle nur konzentriert im Bereich einer Resonanzfrequenz begünstigt, womit allerdings bereits gewisse, erstrebte Betonungen innerhalb des Resonanzspektrums erreichbar sind, ermöglicht die Ueberlagerung verschiedener äquidistanter Reihen von ausgezeichneten Bereichen erhöhter und verminderter Steifheit eine Hervorhebung eines entsprechenden Frequenzbandes. The vibration pattern of a resonance body generally exists from a diverse overlay of standing waves different Wavelength and amplitude. In the node areas there is a slight or vanishing in the abdominal areas a maximum, elastic bending deformation. In the Areas of increased or decreased bending stiffness are consequently the formation of vibration nodes or antinodes favored. While now a simple, equidistant Distribution of areas of increased and decreased stiffness Formation of a standing wave only concentrated in the area of one Favored resonance frequency, which already has certain desired accentuations within the resonance spectrum can be achieved different equidistant overlays Rows of excellent areas increased and decreased Stiffness a highlighting of a corresponding frequency band.

Durch Wahl der Distanzwerte D1, D2 usw. (siehe Fig. 1) der einander überlagerten Reihenfolgen und ihres gegenseitigen Verhältnisses lassen sich die Bereiche des Resonanzspektrums, in denen die Betonungen erscheinen, weitgehend gezielt und reproduzierbar einstellen. Im Interesse eines ausgeglichenen Spektralverlaufes und einer gezielten Einstellung kontinuierlicher Uebergänge können die Steifheitsdifferenzen innerhalb der einzelnen Reihen unterschiedlich bemessen werden, vorteilhaft in der Weise, dass diese Differenzen von Reihe zu Reihe gleichsinnig zum Distanzwert abgestuft sind. Eine solche Ausführung ist in Fig. 1 durch die in ausgezogener Linie wiedergegebene Profilkontur angedeutet. Die Teilkonturen der Folgen R1 und R2 sind dazu strichliert angedeutet. Andererseits kann die Steifheitsdifferenz im Interesse besonders weicher Uebergänge auch innerhalb jeweils einer Reihenfolge variiert werden, etwa in der Weise, dass sie von einem Mittelpunkt des Schwingelementes oder eines Schwingelementabschnitts ausgehend nach beiden Seiten hin abnimmt.
Es ergibt sich dann beispielsweise eine Gliederung G1, wie sie in Fig. 1 strichpunktiert angedeutet ist.
By selecting the distance values D1, D2, etc. (see FIG. 1) of the superimposed orders and their mutual relationship, the areas of the resonance spectrum in which the stresses appear can be set in a largely targeted and reproducible manner. In the interest of a balanced spectral course and a targeted setting of continuous transitions, the stiffness differences can be measured differently within the individual rows, advantageously in such a way that these differences are graduated from row to row in the same direction as the distance value. Such an embodiment is indicated in Fig. 1 by the profile contour shown in solid lines. The partial contours of the sequences R1 and R2 are indicated by dashed lines. On the other hand, in the interest of particularly smooth transitions, the difference in stiffness can also be varied in each case, for example in such a way that it decreases from both sides starting from a center point of the oscillating element or of an oscillating element section.
This then results, for example, in an outline G1, as indicated by dash-dotted lines in FIG. 1.

Fig.2 zeigt ein plattenförmiges Schwingelement SE2 mit Ueberlagerungsgliederung G3 an beiden Oberflächenseiten. Diese Gliederungen entsprechen in ihrem Querschnittsprofil der bereits erläuterten Kanten-Ueberlagerungsgliederung G gemäss Fig. 1. Die Bereiche erhöhter bzw. verminderter Biegesteifheit bilden hier eine Schar von nebeneinanderliegenden, langgestreckten Kämmen bzw. Mulden, die quer zu ihrer Längsrichtung Ueberlagerungsreihen der erläuterten Art bilden.2 shows a plate-shaped vibrating element SE2 with superimposition structure G3 on both sides of the surface. This Outlines already correspond in their cross-sectional profile explained edge superimposition G according to Fig. 1. Die Areas of increased or reduced bending stiffness form one here Group of adjacent, elongated combs or Troughs that are transverse to their longitudinal direction form explained type.

Fig. 3 stellt in schematischer Weise die Möglichkeit einer weiter verfeinerten Oberflächen-Ueberlagerungsgliederung dar, nämlich in Form zweier sich auf einer Oberflächenseite eines plattenförmigen Schwingelementes SE3 kreuzenden Scharen von kammförmigen Bereichen A1, A2, A3 erhöhter Biegesteifheit, die zwei Ueberlagerungsgliederungen G3 und G4 nach Art von Fig.2 bilden. Zwischen den kammförmigen Bereichen ergeben sich muldenförmige Oberflächenbereiche verminderter Biegesteifheit, die der Uebersichtlichkeit halber nicht näher beziffert sind. Gliederungen dieser Art erlauben eine gezielte Beeinflussung der zweidimensionalen, stehenden Wellengebilde und kommen mit grosser Wirksamkeit insbesondere für ausgedehntere Resonanzgebilde in Betracht. Wenn bei dünnwandigen Plattenresonatoren Stellen mit besonders geringer verbleibender Querschnittsdicke vermieden werden sollen, so empfiehlt sich die kreuzende Anordnung je einer Kamm-Muldengliederung auf beiden Oberflächenseiten der Platte.Fig. 3 schematically represents the possibility of a further refined surface overlay outline, namely in the form of two itself on a surface side of a plate-shaped Swinging element SE3 crossing sheets of comb-shaped Areas A1, A2, A3 of increased bending stiffness, the two superimpositions Form G3 and G4 in the manner of Fig.2. There are trough-shaped areas between the comb-shaped areas Surface areas of reduced bending stiffness that the Are not numbered for clarity. Outlines of this type allow the two-dimensional, standing wave formations and come with big ones Efficiency especially for extended resonance structures into consideration. If places with thin-walled plate resonators avoided with a particularly small remaining cross-sectional thickness the crossing arrangement is recommended one each Comb-trough structure on both surface sides of the plate.

Entsprechende Gliederungseffekte können grundsätzlich auch mit Hilfe einer ungleichförmigen Massenverteilung erzielt werden, und zwar insbesondere bei Plattenresonatoren. Unter Annahme einer gleichförmigen Verteilung der Verformungssteifheit kehren sich dabei die bevorzugten Lagen von Wellenknoten und Wellenbäuchen um, d.h. im Bereich erhöhter Schwingmasse ergeben sich bevorzugt Wellenbäuche, im Bereich verminderter Schwingmasse Wellenknoten. Selbstverständlich müssen die Rand-und Einspannbedingungen des Schwingelementabschnitts mit einer solchen Ausbildung vereinbar sein, was aber auch für die Steifheitsgliederungen in sinngemässer Weise gilt. Unter Beachtung dieser Verhältnisse sind mit Vorteil auch kombinierte Steifheits- und Massengliederungen anwendbar. Im übrigen treten - wie bereits angedeutet - ungleichförmige Massenverteilungen im allgemeinen auch bei einer ungleichförmigen Steifheitsverteilung auf. Bei der allgemein anzuwendenden Steifheitsvariation durch entsprechende Bemessung der Querschnittshöhe eines Biegeschwingers tritt jedoch die Wirkung der Massenerhöhung im Bereich erhöhter Querschnitts höhe relativ zurück, weil die Steifheit infolge des Zusammenhanges mit dem Querschnitts-Flächenträgheitsmoment mit einer höheren Potenz der Querschnittshöhe wirksam wird. Die Massenzunahme kann dann vielfach vernachlässigt werden, stört aber jedenfalls im allgemeinen nicht.Corresponding classification effects can also be included With the help of a non-uniform mass distribution, in particular with plate resonators. Assuming a uniform distribution of the stiffness the preferred locations of wave nodes and wave bellies um, i.e. in the area of increased vibrating mass preferably wave bellies, in the area of reduced vibration mass Wave node. Of course, the boundary and clamping conditions must of the vibrating element section with one Training can be compatible, but also for the stiffness structure applies analogously. With this in mind Ratios are also advantageously combined stiffness and Mass breakdowns applicable. For the rest - as already indicated - non-uniform mass distributions in general even with a non-uniform stiffness distribution. In the generally applicable stiffness variation by appropriate However, dimensioning the cross-sectional height of a bending vibrator occurs the effect of the increase in mass in the area of increased cross-section height relatively back because of the stiffness due to the connection with the cross-sectional area moment of inertia with a higher Potency of the cross-sectional height is effective. The mass gain can then be neglected in many cases, but in any case bothers general not.

Andererseits lassen sich Massengliederungen ohne wesentliche Beeinflussung der Steifheit auch herstellungstechnisch günstig mit Hilfe von innerhalb der schwingenden Oberfläche allseitig umgrenzten, also fleckförmigen Erhöhungen bzw. Vertiefungen erzielen. Dazu können letztere insbesondere auch in Form von Durchbrechungen geringerer Flächenausdehnung innerhalb eines plattenförmigen Schwingelementes ausgeführt werden, während für die Bereiche erhöhter Schwingmassenbelegung vorteilhaft die Anbringung von Zusatzmassen in Betracht kommt. Auf diese Weise lassen sich insbesondere auch Steifheits- und Massengliederungen in einer Anordnung mit gegenseitig verstärkender Wirkung vereinigen.On the other hand, mass classifications can be made without essential ones Influencing the stiffness also favorable in terms of production technology with the help of all sides within the vibrating surface delimited, i.e. spot-shaped elevations or depressions achieve. The latter can in particular also in the form of Breakthroughs with a smaller surface area within a plate-shaped vibrating element are executed while advantageous for the areas of increased vibration mass allocation the application of additional masses comes into consideration. To this In particular, stiffness and mass classifications can also be made in an arrangement with mutually reinforcing Combine effect.

Fig.4 zeigt eine sich über die Oberfläche eines plattenförmigen Schwingelementes SE4 erstreckende, rasterförmige Massengliederung G5 mit z.B. kreisförmigen Bereichen AA1, AA2, .... erhöhter Schwingmasse und mit ebensolchen Bereichen BB1, BB2,.... verminderter Schwingmasse. Diese Rasterverteilung entspricht in ihrem Grundaufbau einer zweidimensionalen Gliederung längs sich kreuzender Linienscharen gemäss Fig.3.Fig. 4 shows a plate-shaped surface Vibrating element SE4 extending, grid-shaped mass structure G5 with e.g. circular areas AA1, AA2, .... increased Vibrating mass and with the same areas BB1, BB2, .... reduced vibration mass. This grid distribution corresponds to their basic structure along a two-dimensional structure crossing sets of lines according to Fig. 3.

Fig. 5 zeigt hierzu im Querschnitt die Ausbildung der Bereiche BB1, BB2, .... in Form von Löchern innerhalb des dünnwandigen Plattenelementes und die Ausbildung der Bereiche erhöhter Masse in Form von Zusatzelementen ZM1, ZM2, ZM3, .... . Letztere können z.B. als knopfartige Elemente einfacher Form aufgeklebt werden. Besonders vorteilhaft in der Herstellung ist aber die an den Elementen ZM2 und ZM3 angedeutete Möglichkeit der Aufbringung in Form von dünnen Schichten aus Material hoher Dichte, wofür Schwermetalle und entsprechende Legierungen, insbesondere auch Edelmetalle, in Betracht kommen. Diese Elemente lassen sich bequem in Form von Folienabschnitten herstellen und aufkleben, aber auch in Form von metallgefüllten Formmassen oder Lacken aufbringen. Letzteres bietet den besonderen Vorteil herstellungstechnischer Einfachheit.5 shows in cross section the formation of the areas BB1, BB2, .... in the form of holes within the thin-walled Plate element and the formation of areas of increased mass in the form of additional elements ZM1, ZM2, ZM3, ..... Latter can e.g. glued on as button-like elements of simple shape become. However, the production is particularly advantageous the possibility of the elements ZM2 and ZM3 indicated Application in the form of thin layers of high material Density, for which heavy metals and corresponding alloys, especially precious metals. This Elements can be conveniently shaped in the form of sections of film manufacture and glue, but also in the form of metal-filled Apply molding compounds or varnishes. The latter offers the particular advantage of simplicity in terms of production.

Die Querschnittsgestaltung einer Versteifngsrippe nach Fig.6 beruht auf der Erkenntnis, dass auch in relativ kompakten Gebilden relevante Transversalschwingungen im Festkörper auftreten, im vorliegenden Fall u.a. Biegeschwingungen in verschiedenen Richtungen parallel zur Querschnittsfläche. Stehende Wellen mit Längsrichtung quer zur Rippenlängsrichtung werden dabei durch die gemäss Ueberlagerungsgliederungen G8a, b, c verteilten Bereiche erhöhter bzw. verminderter Biegesteifheit in ihrer Ausbildung entsprechend einer harmonischen Reihe begünstigt. Entsprechende Wirkungen lassen sich mit in den schwingenden Festkörper eingebetteten Bereichen bzw. Elementen ED höherer Dichte gemäss der Rippenausführung nach Fig.7 erzielen, die in Form von zwei sich rechtwinklig durchdringenden Ueberlagerungsgliederungen G9a und G9b angeordnet sind.The cross-sectional design of a stiffening rib according to Fig. 6 is based on the knowledge that even in relatively compact Form relevant transverse vibrations in the solid occur, in the present case i.a. Bending vibrations in different directions parallel to the cross-sectional area. Standing waves with a longitudinal direction transverse to the longitudinal direction of the ribs are determined by the superimposition structure G8a, b, c distributed areas of increased or decreased Flexural rigidity in their training according to a harmonious Row favors. Corresponding effects can be found in the vibrating solid body embedded areas or elements ED higher density according to the rib design according to Fig. 7 achieve that in the form of two intersecting at right angles Superpositions G9a and G9b are arranged.

Fig.8 zeigt nochmals eine Versteifungsrippe mit Kanten- bzw. Querschnitts-Höhengliederung G10a, jedoch mit zu den Enden hin im Mittel abnehmender Querschnittshöhe sowie mit bogenförmiger Gesamtausbildung. Zusätzlich zu den genannten Gliederungen G10a sind an den Flanken der Rippe Ueberlagerungsgliederungen G10b mit in Richtung der Rippenhöhe verlaufenden, wellen- bzw. gratartigen Vertiefungen VT bzw. Erhöhungen EH vorgesehen, und zwar mit bezüglich der Gliederung G8a in Fig.6 mit rechtwinklig versetzter Längserstreckung der Gliederung.Fig. 8 again shows a stiffening rib with edge or Cross-sectional height structure G10a, but with towards the ends on average decreasing cross-sectional height and with an arcuate Overall education. In addition to the outlines mentioned G10a are superimposed on the flanks of the rib G10b with wave or wave ridge-like depressions VT or increases EH provided, and with respect to the structure G8a in Fig. 6 with right angles offset longitudinal extent of the outline.

Fig.9 zeigt eine Ueberlagerungsgliederung an einem ebenen Plattenelement mit rippenförmigen Aufsatz-Versteifungselementen AV. Hier erstreckt sich die Gliederung allein in Richtung quer zu den Rippen. Die einzelnen Rippen sind hier nur mit den Ordnungszahlen 1 bis 8 der entsprechenden Harmonischen bezeichnet, die dem Nenner des Distanz-Teilungsverhältnisses der betreffenden Ueberlagerungsfolge entsprechen. Die Rippenhöhe und damit die Versteifungswirkung nimmt mit der Ordnungszahl ab, was speziell je nach Anwendungsgegebenheiten zu einem ausgeglichenen Resonanzverlauf beitragen kann. Eine solche im wesentlichen eindimensionale Gliederung begünstigt die Ausbildung von Stehwellen nur in einer Richtung der Platte.Fig. 9 shows an overlay structure on a plane Plate element with rib-shaped attachment stiffening elements AV. Here the structure extends in the direction transverse to the ribs. The individual ribs are here only with the ordinal numbers 1 to 8 of the corresponding harmonics designated the denominator of the distance division ratio of the concerned Overlap sequence. The rib height and thus the The stiffening effect decreases with the atomic number, which is special depending on the application conditions to a balanced Resonance course can contribute. Such an essentially one - dimensional structure favors the formation of Standing waves only in one direction of the plate.

Es ist hervorzuheben, dass durch die erfindungsgemässen Gliederungen - je nach spezieller Ausbildung - nicht nur eine gezielte Tendenz zur Bildung von Stehwellenknoten bzw. Stehwellenbäuchen erzielt werden kann. Vielmehr gilt entsprechendes auch für eine angestrebte Verteilung der Schwingungsdämpfung. Hierfür sind sinngemäss geeignete Dämpfüngselemente in einer schwingungsaktiven Gliederung einzusetzen.It should be emphasized that the inventive Outlines - depending on special training - not just one targeted tendency to form standing wave nodes or Standing antinodes can be achieved. Rather, the same applies also for a targeted distribution of vibration damping. Suitable damping elements are appropriate for this to be used in a vibration-active structure.

In the form of recesses, a corresponding one is obvious Cover provided that is not vibration-active Needs to have an effect. Fig. 14 shows schematically one active vibration extending in the vertical direction of the ski cross-section HX structure in the form of lamellar, stiffening and / or mass-increasing inserts in the ski body. Essential is the structure of the structure for all these versions, namely a multiple overlay structure according to the type of Fig. 1.

The structure according to Figures 12 to 14 influence especially the behavior of the ski with regard to torsional vibrations.

Erwähnenswert ist auch ein intensivierter sensorischer Kontakt des Fahrers mit der jeweiligen Bahnbeschaffenheit. Gleitkörper dieser Art können insbesondere vorteilhaft mit Gliederungen versehen werden, die sich aus bis zu fünf überlagerten Reihen unterschiedlicher Teilung zusammensetzen.

Als Beispiele für zahlreiche Anwendungen im Bereich der Medien-Gleitkörper sind in den Figuren 15 und 16 rein schematisch Bootskörper im Quer- bzw. Längsschnitt angedeutet, und zwar jeweils mit sich in Backbord/Steuerbord-Richtung bzw. in Kielrichtung erstreckenden Überlagerungsgliederungen BSX bzw. KLX.
