Abstract
The invention relates to a tuning rotational inertia damping vibration attenuation device. The tuning rotational inertia damping vibration attenuation device comprises a rotational inertia mass block, a torsion damper and a rotating restoring force providing mechanism. One end of the rotating restoring force providing mechanism and one end of the tension damper are fixedly connected to a structure, and the other end of the rotating restoring force providing mechanism and the other end of the tension damper are connected to the rotational inertia mass block. The rotational inertia mass block is parallel to the rotating surface of the structure, the rotating restoring force providing mechanism is perpendicularly connected with the rotational inertia mass block, and the torsion damper is perpendicularly connected with the rotational inertia mass block. By the adoption of the structure, because the rotational inertia mass block parallel to the rotating surface of the structure is arranged, when the structure moves in a rotating mode, rotating motion can be transmitted to the rotational inertia mass block through the rotating restoring force providing mechanism, and accordingly the torsion damper is driven, the energy of the rotating motion is absorbed by the torsion damper, and the tuning rotational inertia damping vibration attenuation device has a very good damping effect.
Description
Technical field
The present invention relates to a kind of frequency modulation rotary inertia damping device control system that is used for structure rotational motion control with revolution or the work of rotational motion form, is the TRID system hereinafter to be referred as this new control system.
Background technique
Along with development economic and society, the dynamics of country's annual input civil engineering and infrastructure construction is increasing, tall building, Longspan Bridge, large-scale stadium, nuclear power station, some significant Important Project such as offshore oil drilling platform are built in a large number, be that a large amount of civil engineering structure of representative all will stand various load actions inevitably in construction He in the using process with them, comprising dead load and dynamic load, dynamic load such as earthquake, wind etc., also to stand oceanic winds for offshore engineering structure, wave, the effect of stream joint incentive, and the sea ice effect in winter.These dynamic loads all can cause structural vibrations to the effect of structure, bring fatigue and integrity problem, threaten the safety of structure, when serious structure are destroyed, and cause economic loss and casualties.For example, under geological process, the earthquake response at some position of structure (as acceleration, displacement etc.) is excessive, to make the heavy damage of main body bearing structure even collapse, though perhaps agent structure is not destroyed, non-structural elements such as decorations damage and cause structure can't continue to use, though perhaps agent structure and non-structural element do not destroy, but indoor expensive instrument, the damage of equipment and cause serious loss or produce secondary disaster, these disasters all can cause enormous economic loss.Nineteen ninety-five Japan slope earthquake centre celestially for example, death toll only is 5000 people, and direct economic loss is up to 1,000 hundred million dollars, indirect economic loss is more up to more than 2,000 hundred million dollars.
On the other hand, the progress with structure construction technology of continuing to bring out along with New Building Materials, structural material more and more develops towards the high-strength light direction, the free vibration period of structure that construction is come out is longer, damping is littler, more responsive to environmental load (for example wind), dynamic response is more outstanding, and this structure not only needs to consider intensity design, sometimes rigidity and comfortableness problem also may become the restraining factors of structural design, must take in.
The structural vibration control technology that grew up in the last few years is the focus direction of area researches such as civil engineering and Aero-Space, automobile, machinery, military engineering always, for civil engineering structure, vibration control system is installed in structure rightly can be reduced the dynamic response of structure effectively, alleviate destruction or the fatigue damage of construction element, reach the reasonable balance of Economy, Security and reliability.For example, for offshore platform structure, there are some researches show, adopt vibration control technology to make platform structure dynamic stress amplitude reduce 15%, structural life-time is prolonged more than the twice, the detection of ocean platform and the maintenance cost under the normal use condition are reduced significantly, have important and practical meanings.Studies show that in a large number: structural vibration control can alleviate reaction and the damage of structure under dynamic actions such as wind, wave, stream, ice and earthquake effectively, improve the performance of combating a natural disaster of structure effectively, is the active and effective countermeasure that structure combats a natural disaster to prevent and reduce natural disasters.
The history of the research of vibration control of civil engineering structure and existing over half a century of application can be divided into following four main aspects: Passive Control, ACTIVE CONTROL, half ACTIVE CONTROL and intelligent control, and mix control.Passive Control is simple in structure because of it, cost is cheap, be easy to safeguard and need not the extra power input etc. advantage paid close attention to widely, its main application form has: basic vibration isolation, passive energy dissipation and tuning absorbing vibration damping etc., the device that wherein is used for passive tuning absorbing control mainly comprises: tuned mass damper (Tuned Mass Damper, TMD) and Tuned Liquid (Tuned Liquid Damper, TLD) etc.
The principle of structural vibration TMD control is in the additional control subsystem (second-order system) of main structure (first-order system), comprise: quality, spring and damping etc., frequency by the modulator structure reaches consistent with the main structure frequency or is close, the vibration of main structure causes subtense angle resonance, damper mechanism dissipative structure vibrational energy by subtense angle inside, thereby subdue the dynamic response of main structure, reach the purpose of control main structure vibration.The TMD control system is used to reduce the vibration that mechanical system motion produces at first, is commonly called as dynamic vibration absorber DVA (Dynamic VibrationAbsorber), begins the control of shaking of wind for building structure the seventies in 20th century.Existing result of study shows: the TMD control system can both play good control effect aspect wind induced structural vibration response and the seismic response resisting.Existing many buildings building structure adopts the TMD control system to reduce the wind vibration response of structure in the world at present, for example: heavy 360 tons TMD has been installed in the 274 meters high World Trade Centre building that has collapsed in the USA New York at the top, two heavy TMD of 300 tons have also been installed at 58 layers in the John Hancock building that boston, u.s.a in 1976 is 60 layers, after this have hundreds of high buildings, high tower that the TMD control system has been installed successively and reduce the wind induced structural vibration response.Until today, the highest two the Malaysian Kuala Lumpur double tower Twin Tower of building in the world and 101 buildings, Chinese Taibei have also been installed the TMD control system respectively and have been reduced the wind induced structural vibration response.A large amount of practices have confirmed that the TMD system has good, stable control effect.
Yet find when adopting TMD system control suspention quality control vibration problems: when structure suspension direction is consistent with its lagging motion direction, no matter be that the TMD system can both bring into play effective control action under initial offset or simple harmonic quantity load excitation input; Namely hang direction when mutual vertical with its lagging motion direction when structure when the TMD system being used for the shimmy control of another direction of structure, adjust system parameter (as structure pendulum length, control system position etc.) in any case, the TMD system can't work all the time.Explore through a large amount of theory analysis and test, proposed translational motion that translation TMD control system can only control structure and to turning round the invalid conclusion of shimmy control.
The motion of various structural systems all is subjected to effect and the influence of gravity field inevitably, for example, the unrestricted motion of one class single pendulum suspension structuress such as lifting pipe laying barge hanger system gib head structure in gravity field controlled or encouraged the gib head diriven motion that causes to control owing to boats and ships are subjected to wave, and a class such as floating deep water offshore platform structure is similar to the reversely standing pendulum structural system at wind, float control under load such as wave and the synergy thereof, or the vibration control of tall and slender structure flexible bending etc., therefore through a large amount of theory analysis and calculating, find to adopt traditional structural vibration control means, for example (X or Y-direction) applies linearity control power in the horizontal plane vertical with the gravity field direction, as adopt passive tuned mass damper (English name Tuned Mass Damper, be called for short TMD) or Tuned Liquid (English name Tuned Liquid Damper, be called for short TLD) control system, or even active mass damper/driver (English name Active Mass Damper/Driver is called for short AMD) control system all is difficult to achieve effective control or controls effect relatively poor.Its basic reason is that this moment, passive control system such as TMD, TLD were in apocarpy and ineffective, mass of system piece (or the water in the TLD water tank) does not move, and AMD system active controlling force makes the big heavy discount of its control efficiency because needs overcome the mass block weight component.Therefore must design a kind of special structural vibration/kinetic control system, make it can overcome (or breaking away from) gravity field automatically to the influence (centrifugal action) of control system self, perhaps make work/characteristics of motion and the gravity field decoupling zero of control system self, system's self-vibration is not subjected to gravity effect, more than two aspects all can reach the purpose that the control system sufficient movement is got up, thereby the performance control system is to effective control action of structure motion/vibration.
The present invention produces under such demand background.
