Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Einrichtung zur Prüfung von wenigstens einem Bauteil auf seine Belastbarkeit gegenüber hydraulischen Druckpulsationen entsprechend den gattungsbildenden Merkmalen des Anspruchs 1.The The invention is based on a device for testing at least one component to its capacity over Hydraulic pressure pulsations according to the generic Features of claim 1.
Derartige Prüfeinrichtungen werden beispielsweise bei der Komponentenentwicklung und -erprobung eingesetzt mit dem Ziel, die Funktionstüchtigkeit von Bauteilen unter realitätsnahen Einsatzbedingungen zu untersuchen, Schwachstellen einer Konstruktion bereits im Vorfeld einer Serienherstellung aufzudecken oder mögliche technische Verbesserungen an einer bestehenden Konstruktion auf ihre Tauglichkeit und auf ihre Dauerhaltbarkeit hin zu untersuchen.such Testing equipment, for example, in the development of components and testing used with the goal of functioning of components under realistic operating conditions Investigate vulnerabilities of a design in advance to uncover a serial production or possible technical Improvements to an existing design for their suitability and their durability.
Bekannte Prüfeinrichtungen umfassen zu diesem Zweck einen Hydraulikkreis mit einer extern antreibbaren Hydraulikpumpe. Diese saugt Druckmittel aus einem Vorratsbehälter an, verdichtet dieses Druckmittel und fördert es unter erhöhtem Druck zu einer Aufnahmevorrichtung in der zu prüfende Bauteile verankert sind. Zur Erzeugung des Prüfdrucks ist der Hydraulikpumpe ein Druckübersetzer nachgeordnet, welcher den vom Druckerzeuger abgegebenen Druck verstärkt. Bei diesem Druckübersetzer kann es sich um zwei Hydraulikzylinder unterschiedlich großer Außendurchmesser handeln, die mechanisch miteinander gekoppelt sind. Der im Außendurchmesser größere Hydraulikzylinder ist dabei dem Druckerzeuger zugewandt. Weiterhin sind im Hydraulikkreis Mittel vorhanden, die Druckpulsationen erzeugen. Dabei handelt es sich beispielsweise um elektromagnetisch ansteuerbare Ventile oder um extern betätigbare Kolben-/Zylinder-Einheiten. Durch Variation des Pumpenantriebs, der Betätigungsfrequenz und/oder des Betätigungshubs der Druckpulsationen erzeugenden Mittel lässt sich die Charakteristik der erzeugten Druckpulsation bedarfsgerecht anpassen.Known Test devices include for this purpose a hydraulic circuit with an externally driven hydraulic pump. This sucks pressure medium from a reservoir, compresses this pressure medium and promotes it under increased pressure to a cradle are anchored in the components to be tested. To produce the test pressure of the hydraulic pump is a pressure booster downstream, which amplifies the pressure exerted by the pressure generator. This pressure booster can be two hydraulic cylinders act differently sized outer diameter, which are mechanically coupled together. The outside diameter larger hydraulic cylinder is the pressure generator facing. Furthermore, in the hydraulic circuit means are present, the Generate pressure pulsations. These are for example Electromagnetically controllable valves or externally operable Piston / cylinder units. By varying the pump drive, the actuation frequency and / or the Betätigungshubs the pressure pulsation generating means can be the Adjust the characteristic of the generated pressure pulsation as needed.
Nachteilig bei bekannten Prüfeinrichtung ist der erhebliche bauliche Aufwand, den der Einsatz von Druckübersetzern und von Druckpulsationen erzeugenden Mitteln mit sich bringt.adversely in known test device is the considerable structural Expenditure, the use of pressure intensifiers and pressure pulsations generating means.
Vorteile der ErfindungAdvantages of the invention
Demgegenüber weist eine Einrichtung entsprechend den Merkmalen des Anspruchs 1 den Vorteil auf, dass sie kostengünstiger und kompakter im Aufbau ist. Mit ihr lassen sich Druckpulsationen über ein breites Frequenz- und Druckspektrum relativ einfach darstellen, wobei störende niederfrequente Schwingungen weitestgehend vermieden werden. Zudem erlaubt eine erfindungsgemäße Prüfeinrichtung einen automatischen Ausgleich eventuell vorhandener Leckage und damit konstantere Prüfungsbedingungen.In contrast, comprises a device according to the features of the claim 1 has the advantage that it is cheaper and more compact is under construction. With it, pressure pulsations can be over represent a wide frequency and pressure spectrum relatively easily, disturbing low-frequency vibrations as far as possible be avoided. In addition, an inventive allows Checking device may automatically compensate existing leakage and thus more constant test conditions.
Weitere Vorteile oder vorteilhafte Ausbildungen der Prüfeinrichtung nach Anspruch 1 ergeben sich aus den Unteransprüchen oder der nachfolgenden Beschreibung.Further Advantages or advantageous embodiments of the test device according to claim 1 emerge from the dependent claims or the following description.
