Description
Technical field
The present invention relates to a kind of resistance of the frequency modulation rotary inertia for structure rotational motion control with revolution or the work of rotational motion formBuddhist nun's apparatus control system is TRID system hereinafter to be referred as this new control system.
Background technology
Along with economical and social development, the dynamics of country's annual input civil engineering and infrastructure construction is increasing, high levelSome significant Important Project such as building, Longspan Bridge, large-scale stadium, nuclear power station, offshore oil drilling platform are a large amount ofBuild, a large amount of civil engineering structure taking them as representative all inevitably will stand various in construction and in use procedureThe load action of various kinds, comprising dead load and dynamic load, dynamic load, as earthquake, wind etc., is also wanted for offshore engineering structureStand the effect of oceanic winds, wave, stream joint incentive, and the sea ice effect in winter. These dynamic loads to the effect of structure allCan cause the vibration of structure, bring fatigue and integrity problem, threaten the safety of structure, when serious, will make structure destroy,Cause economic loss and casualties. For example, under geological process, the earthquake response at some position of structure is (as acceleration, displacementDeng) excessive, will make the heavy damage of main body load-carrying members, even collapse, though or agent structure do not destroy, decorations etc. are non-Structural elements damages and causes structure cannot continue to use, although or agent structure and non-structural element do not destroy, indoorThe damage of expensive instrument, equipment and cause serious loss or produce secondary disaster, these disasters all can cause huge economy to damageLose. For example nineteen ninety-five Japan slope earthquake centre celestially, death toll is only 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, along with continuing to bring out and the progress of structure construction technology of New Building Materials, structural material more and more towardsHigh-strength light future development, consequently makes to build that free vibration period of structure is out longer, damping is less, to environmental load (exampleAs wind) more responsive, dynamic response is more outstanding, this structure not only needs to consider intensity design, sometimes rigidity andComfortableness problem also may become the restraining factors of structural design, must take in.
The structural vibration control technology growing up is in the last few years civil engineering and Aero-Space, automobile, machinery, army alwaysThe focus direction of the area researches such as thing engineering, for civil engineering structure, in structure, vibration control system being installed rightly canEffectively reduce the dynamic response of structure, alleviate destruction or the fatigue damage of structural elements, reach economy, security and reliableThe reasonable balance of property. For example, for offshore platform structure, there are some researches show, adopting vibration control technology that platform structure is moved shouldPower amplitude reduces 15%, more than can making structural life-time prolongation twice, also can make detection and the normal feelings that use of ocean platform simultaneouslyMaintenance cost under condition significantly reduces, and has important practical significance. Large quantity research shows: structural vibration control can be effectiveGround alleviates reaction and the damage of structure under the dynamic actions such as wind, wave, stream, ice and earthquake, effectively improves the combating a natural disaster property of structureCan, be 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 mainAspect: Passive Control, ACTIVE CONTROL, half ACTIVE CONTROL and Based Intelligent Control, and mix and control. Passive Control is because of its structure letterSingle, cost is cheap, be easy to safeguard and need not extra power input etc. advantage and being paid close attention to widely, its main application form has:Basis vibration isolation, passive energy dissipation and tuning absorbing vibration damping etc., wherein mainly comprise for the device of passive tuning absorbing control: tuningMass damper (TunedMassDamper, TMD) and Tuned Liquid (TunedLiquidDamper, TLD)Deng.
The principle that structural vibration TMD controls is at the upper additional RACS (second-order system) of main structure (first-order system), bagDraw together: quality, spring and damping etc., reached consistent with main structure frequency or be close by the frequency of modulator structure, main structureVibration cause subsystem resonance, by the damper mechanism dissipative structure vibrational energy of subsystem inside, thereby subdue main structureDynamic response, reaches the object of controlling main structure vibration. TMD control system is used to reduce that mechanical system motion produces at firstVibration, is commonly called as dynamic vibration absorber DVA (DynamicVibrationAbsorber), and 20 century 70s start for building knotThe control of shaking of the wind of structure. Existing result of study shows: TMD control system is being resisted aspect wind induced structural vibration response and seismic response allCan play good control effect. The building structure of existing many buildings adopts TMD control system to reduce the wind of structure in the world at presentVibration response, for example: the World Trade Centre building of 274 meters high that collapsed in USA New York has been installed heavy 360 tons at topTMD, two heavy TMD of 300 tons have also been installed in the JohnHancock building that boston, u.s.a in 1976 is 60 layers on 58 layers,After this there are successively hundreds of high buildings, high tower that TMD control system has been installed and reduce wind induced structural vibration response. Until today, the worldTMD control has also been installed respectively in high two Malaysian Kuala Lumpur double tower TwinTower of building and 101 buildings, Chinese TaibeiSystem reduces wind induced structural vibration response. A large amount of practices have confirmed that TMD system has good, stable control effect.
But find while adopting TMD system control suspended mass system vibration problems: when structure hangs direction and its lagging motionWhen direction is consistent, no matter be that TMD system can be brought into play effective control and do under initial offset or Simple Harmonic Load excitation inputWith; When TMD system is worked as for the shimmy control of another direction of structure, structure hangs direction and its lagging motion direction is mutualWhen vertical, adjustment System parameter (as structure pendulum length, control system position etc.) in any case, TMD system cannot be worked all the time.Through a large amount of theory analysis and experimental exploration, translational motion that translation TMD control system can only control structure is proposed and rightTurn round the conclusion that shimmy control is invalid.
The motion of various structural systems is all inevitably subject to effect and the impact of gravitational field, for example, and lifting pipe laying vessel suspension hook systemThe freely-movable control of a class single pendulum suspended structure such as system hook head structure etc. in gravitational field or cause because boats and ships are subject to wave excitationThe control of gib head diriven motion, and a class such as floating deep water offshore platform structure is similar to inverted pendulum structural system at wind, waveDeng the float control under load and synergy thereof, or the vibration control of tall and slender structure flexible bending etc., therefore through excessiveTheory analysis and the calculating of amount, find to adopt traditional structural vibration control means, for example, in the level vertical with gravitational field direction(X or Y-direction) applies Linear Control power in face, as adopt passive tuned mass damper (English name TunedMassDamper,Be called for short TMD) or Tuned Liquid (English name TunedLiquidDamper, be called for short TLD) control system, veryTo being all difficulties of active mass damper/driver (English name ActiveMassDamper/Driver is called for short AMD) control systemPoor with achieve effective control or control effect. Its basic reason be now the passive control system such as TMD, TLD inApocarpy and ineffective, motion of System Nature gauge block (or water) in TLD water tank, AMD system ACTIVE CONTROLPower makes the large heavy discount of its control efficiency because needs overcome mass weight component. Therefore a kind of special structural vibration of necessary design/Kinetic control system, makes it can automatically overcome the impact (centrifugal action) of (or breaking away from) gravitational field on control system self,Or make work/characteristics of motion and the gravitational field decoupling zero of control system self, system self-vibration is not affected by gravity, above two aspectsAll can reach the object that control system sufficient movement is got up, thus the effective control of performance control system to structure motion/vibrationEffect.
The present invention produces under such requirement background.
