Technical field
The present invention relates to damping device, more particularly to the damper using disk spring group.
Background technology
Damper is a kind of to provide the damping device that the resistance of motion carrys out depletion kinergety.Using damper come energy-absorbing
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 so that 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 in the presence of weak wind shake and small earthquake
Rigidity resists the effect of external load, the integrality of retainer body structure, avoids main structure body from internal injury occur, and strong
Anti-seismic structure then starts yield deformation in the presence of wind shake and violent earthquake, by the damping action of the damper in anti-seismic structure come
Dissipation external energy, main structure body is shaken in high wind and is unlikely to be seriously damaged in violent earthquake or even collapses, ensure people's
Safety of life and property.This just requires that rigidity can be kept in the presence of outside weak load by being applied to anti-seismic structure, not become
Shape, power consumption can be then deformed in the presence of outside strong load.But existing spring-damper can not also meet above-mentioned antidetonation need
Ask, any spring-damper 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 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.
According to《Analysis of Basic Characteristic Parameters of Disk Springs》Author Yi Xianzhong theory analysis, the natural frequency of vibration of monolithic disk spring(in formula, KpFor rigidity, msFor the quality of disk spring, m is the quality of object of being connected with disk spring, ξ
For equivalent quality transformation ratio) [see,《Petroleum machinery》Magazine, the phase the 10th of volume 23 the 3rd nineteen ninety-five to wait page 22], it is seen then that when
After the quality of disk spring and the Quality Design for the object that is connected with disk spring determine, the disk spring natural frequency of vibration square with it is upper
The rigidity of disk spring is directly proportional.

Nut is mutually drawn close or the pretightning force away from i.e. adjustable two groups of disk springs is so as to adjust the damped coefficient of damper, to meet
The use demand of different frequency and various amplitude.But the invention still has following deficiency：
1st, the load connecting rod is that balance is kept under the collective effect of two groups of disk springs, two groups of disk springs
Although pretightning force can be adjusted, adjust anyway, two groups of disk springs are all one group to the active force of load connecting rod
Power equal in magnitude, in opposite direction, only need to apply any external force in load connecting rod can all destroy this balance, make two groups of dish
Shape spring deforms, so described 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 the length of damper is greatly added, and is not suitable for some installing spaces
Compact occasion uses.
Publication No. CN101457553A application for a patent for invention discloses one kind, and " spring stiffness adjustable tuning quality subtracts
Shake device ", the shock absorber is a kind of composite buffer, and the thickness by changing mass changes its characteristic frequency, viscous by changing
The flow of the working media of stagnant damper changes its damping ratio, changes its rigidity by the effective active length for changing spring, its
The means of the middle effective active length for changing spring have three kinds, first, using one section of curing materials by spring in solidification cylinder
Solidification, second, toward constraint block, and the two interference fit is filled in the center of helical spring, make the one section of spring contacted with constraint block
Failure, third, setting helical raised on constraint block surface, between helical raised is stuck in into spring wire, make to block between spring wire
There is one section of spring failure of helical raised.As can be seen here, although the spring in the patent application scheme can change rigidity, institute
Not only effective active length substantially shortens the spring stated, and can only compress passive energy dissipation, it is impossible to stretches passive energy dissipation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of disk spring damper of predeterminable early stage rigidity, the dish
