Background technology
Antivibrator is the damping device that a kind of resistance to provide motion carrys out depletion kinergety.Using antivibrator come energy-absorbing
Damping is a kind of conventional art being widely used in space flight, aviation, military project, firearms and automobile and other industries.From twentieth century
Since the seventies, people start progressively using antivibrator energy-absorbing damping technology application to building, bridge, railway etc. tie
In structure engineering.And disk spring antivibrator is widely used in the characteristic of its impact resistance height, low cost, good damping effect
In the anti-seismic structure of various buildings.
The design of the anti-seismic structure for building especially skyscraper for the people is pursued one kind " resisting " and is combined with " consumption "
Comprehensive anti-seismic performance, that is, in the presence of weak wind shake and small earthquake anti-seismic structure to be that building main body provides extra additional
Rigidity resisting the effect of external load, the integrity of retainer body structure, it is to avoid internal injury in main structure body, and strong
In the presence of wind shake and violent earthquake, anti-seismic structure then starts yield deformation, by the damping action of the antivibrator in anti-seismic structure Lai
Dissipation external energy, make main structure body high wind shake and violent earthquake in be unlikely to be seriously damaged or even collapse it is ensured that people
Safety of life and property.This just requires to be applied to anti-seismic structure and can keep rigidity in the presence of outside weak load, does not become
Shape, then can deform power consumption in the presence of outside strong load.But existing spring-damper also cannot meet above-mentioned antidetonation need
Ask, any spring-damper all can produce more or less elastic deformation in the presence of external load.Therefore above-mentioned people institute
The performance of the Antiseismic building structure pursued is difficult to realize.
In addition, the effect of seismic wave is in multidirectional randomness, i.e. act on the size direction of power on building and frequency is all
Random, the antivibrator that thus be accordingly used in antidetonation need to meet following two requirements: one be antivibrator characteristic frequency defeated with earthquake
