Description
Technical field
The inhibition field that the utility model relates to vibrate in system, in particular to a kind of rotation of band damping liquid case
Inertia active control device.
Background technique
In recent years, it is also continuously improved with social progress, requirement of the people to living space with the development of economy, country
Investment in terms of infrastructure constantly increases.Country is increasing in the investment of civil engineering, highway, railway, bridge,
Skyscraper, large-span space structure etc. are constantly built.In addition to this, people, which also explore, develops broader space, to " deeply
Sea ", " deep space " are explored, and the structures such as ocean platform, space station are also quickly grown.These space structures, construction and after
Phase runs in use process, all inevitably effects by various loads, including dead load and dynamic load.In making for structure
With in the process, to the often Under Dynamic Load, such as earthquake, wind, wave, stream, ice, explosion that structure is affected, structure is at these
Vibration can be generated under the action of dynamic load, can be caused fatigue and integrity problem under normal circumstances, be will cause structure when serious
Damage inactivation, cause casualties and property loss.Structure in use, after Under Dynamic Load, such as geological process,
Structure generates collapse, can not continue to use, or even if structure is not collapsed, but its internal installations and facilities, decoration fill
It repairs, can not also continue to use after installation system is destroyed, or even cause secondary disaster, this causes huge to user of service
Security threat and economic asset loss.
On the other hand, it is constantly progressive with the development of economy with technology, requirement of the people to structure no longer only office
Be limited to can be used, also safety of structure, in terms of more stringent requirements are proposed.People in the use process of structure,
Works does not only need to ensure that the life security of people, it is also necessary to meet requirement of the people to comfort level etc..Such as, high-rise knot
Structure can generate vibration under wind action, in the case where not subtracting isolation measure, can feel to tie in high-rise user
The shaking of structure object, in the biggish situation of wind-force, the installations and facilities inside works even will receive vibrated as works caused by
It destroys, this is not only unable to satisfy people to the comfort requirement of works, also threatens to economic asset.
It is various caused by being vibrated by works in order to solve the problems, such as, it eliminates or mitigates and vibrated as caused by external loads, shaken
Dynamic control technology is rapidly developed in recent years.Be not only in field of civil engineering, vibration control technology aerospace,
The fields such as automobile, machinery, ocean engineering, military engineering are also hot spot direction.For civil engineering structure, in the structure properly
Safe vibration control apparatus can effectively mitigate the dynamic response of structure, mitigate structural damage or fatigue damage, thus
Meet people to the demands such as safe, comfortable of structure, reaches the reasonable balance of safety, economy, reliability.Numerous studies table
Bright, vibration control technology has significant effect and important meaning in the application of civil engineering, can not only prevent or mitigate
Structural damage improves the performance of taking precautions against natural calamities of structure, guarantees the security of the lives and property of people, can be reduced with the extending structure service life
The maintenance cost of structure greatly meets the comfort level requirement of people under extreme conditions to structure.
In terms of vibration control of civil engineering structure technology is broadly divided into following four: active control, passive control, half are actively
Control and mixing control.Wherein, the research of passive control technology have been relatively mature, wherein the dress for passively tuning energy-absorbing
Setting mainly includes tuned mass damper and Tuned Liquid etc., is answered in many civil engineering structures
With.TMD control principle be it is consistent or close with main structure i.e. controlled structures by adjusting the minor structure i.e. frequency of damper, make
Minor structure and main structure resonate, by the internally-damped mechanism dissipation main structure vibrational energy of minor structure, so that it is dynamic to cut down main structure
Force-responsive achievees the purpose that vibration control.A large amount of research and practical application are it has been shown that for example: 60 layers of boston, U.S.A
The building John Hancock, Malaysian Kuala Lumpur Petronas Towers, 101 building of Chinese Taibei be respectively mounted TMD vibration control dress
It sets, there is stable, good control effect by the passive control TMD system of the application attestation in the later period.
The forms of motion of structure has complicated and diversified characteristic, is usually composed of translation and torsionoscillation.However
It is found when controlling suspended mass system vibration problems using TMD system: when structure suspension direction is consistent with its lagging motion direction
When, either under initial offset or Simple Harmonic Load excitation input, TMD system can play effective control action；Work as handle
TMD system is used for the shimmy control in another direction of structure i.e. when structure suspension direction and its lagging motion direction are mutually perpendicular to,
System parameter (such as structure pendulum length, control device position) is adjusted in any case, TMD system can not work always.By a large amount of
Theory analysis and experimental exploration, propose translation TMD control device can only control structure translational motion and to turn round it is shimmy
Control invalid conclusion.By scholar's studies have shown that its basic reason is that the passive control devices such as TMD, TLD are at this time
Apocarpy and it is ineffective, System Nature gauge block (or water in TLD water tank) does not move or even active mass damper/
Driver (English name Active Mass Damper/Driver, AMD) control device active controlling force is because needing to overcome mass block
Weight component and make the big heavy discount of its control efficiency.However have the structure motion form for turning round shimmy kinetic characteristic extremely normal
See, such as: torsion of the asymmetric buildings under wind action is shimmy；The swing of overhung construction；Ocean platform is in wave, wind, ice
Wait the torsion under couplings shimmy etc..Therefore it needs to design a kind of special structural vibration/motion control device, allow to
Automatically overcome influence (centrifugal force effect) of (or getting rid of) gravitational field to control device itself, or make the work of control device itself
Work/characteristics of motion and gravitational field decouple, and system self-vibration is not influenced by gravitation, and can achieve in terms of two above makes control device
The purpose that sufficient movement gets up, to play control device to the effective control action of structure motion/vibration.
In conclusion existing structural vibration control device/system is in the indispensable using having of field of civil engineering
Effect, and to ensure structure user life and property have very important significance.But existing structural vibration
Control device/system mainly shows the deficiency of following several respects: first, translation TMD control device can only control structure it is flat
It moves movement and controls in vain revolution is shimmy；Second, although translation AMD control device can control revolution shimmy, but control
Efficiency is extremely low, is unable to satisfy requirement；Third, passive rotation inertia tuned damper is effective to shimmy motion control is turned round,
But it needs to carry out complicated frequency modulation for structure itself, and it is lower to certain labyrinth control efficiencies, it is ineffective, exist
The disadvantages of robustness is low, and controllability is low, and the scope of application is small；4th, actively the immutable damping control apparatus scope of application is small, control
Power output is limited, and control effect is limited；5th, the immutable control device energy utilization rate of active damping not can guarantee, can not
Meets the needs of economy.
