Damping is a kind of conventional art for being widely used in space flight, aviation, military project, firearms and automobile and other industries.From twentieth century
Since the seventies, the technology using damper energy-absorbing damping is applied to building, bridge, railway etc. that people start progressively are tied
In structure engineering.And disk spring damper is with its impact resistance is high, cost is low, good damping effect characteristic is widely used in
In the anti-seismic structure of various buildings.
Design of the people for the anti-seismic structure of building especially skyscraper is pursued a kind of " anti-" and is combined with " consumption "
Synthesis anti-seismic performance, i.e., anti-seismic structure can provide extra additional for building main body under the action of weak wind shake and small earthquake
Rigidity resists the effect of external load, and the integrality of retainer body structure, avoids main structure body from internal injury occur, and strong
Anti-seismic structure then starts yield deformation under the action of wind shake and violent earthquake, by the damping action of the damper in anti-seismic structure come
Dissipation external energy, makes main structure body shake in high wind and be unlikely to be seriously damaged in violent earthquake or even collapse, ensures people's
Safety of life and property.This just requires that rigidity can be kept under the action of exterior weak load applied to anti-seismic structure, does not become
Shape, energy consumption can be then deformed under the action of exterior intense loading lotus.But existing spring-damper can not also meet above-mentioned antidetonation need
Ask, any spring-damper can produce more or less elastic deformation under the action of external load.Therefore above-mentioned people institute
The performance of the Antiseismic building structure of pursuit is difficult to realize.
In addition, the effect of seismic wave is in multidirectional randomness, i.e. the size direction and frequency for acting on power on building are all
Random, thus be accordingly used in the damper of antidetonation need to meet following two requirements：First, the characteristic frequency of damper is defeated with earthquake
The resonance frequency domain for entering excitation staggers, second, the characteristic frequency of damper will stagger with building or the characteristic frequency of building structure.

Shape spring deforms, so the damper can not preset early stage rigidity；
2nd, by changing the damped coefficient of disk spring to two groups of disk spring precompressed, it is this change it is extremely limited, this
Cause the equivalent stiffness adjustable range of damper small, can not often meet requirement of the architectural vibration-insulation for frequency；
3rd, two groups of disk springs must be used cooperatively in the invention, could all be provided when damper is pressed or draws load
Damping, this not only causes certain waste, also so that the length of damper greatly adds, is not suitable for some installation spaces
