Damping method and damping device based on tension-torsion coupling effect

Abstract

The invention provides a shock absorbing method and a shock absorbing device based on the tension-torsion coupling effect. The invention relates to the field of mechanical shock absorbing, wherein the method includes: when the upper side of the first end plate is impacted, using The first end plate moves toward the direction of the turntable to shorten the distance between the first end plate and the turntable; when the distance between the first end plate and the turntable is shortened, the first end plate drives the turntable through the transmission of the transmission rod The rotation of the elastic member is performed while the elastic member is compressed; the damping fluid passing through the filling chamber prevents the rotation of the turntable; after the impact is over, the elastic potential energy stored in the elastic mechanism is released to restore the first end plate and the turntable to their original positions, and at the same time The damping fluid passing through the filling chamber prevents the rotation of the turntable. The problem of how to avoid the secondary damage caused by the elastic member to the shock-absorbing object during the shock-absorbing process is solved.

Description

technical field [0001] The present invention relates to the field of mechanical damping, and more specifically, to a damping method and a damping device based on tension-torsion coupling effect. Background technique [0002] Shock absorber is a kind of mechanical equipment commonly used to absorb external shocks. The earliest shock absorber just refers to the spring with a high elastic coefficient arranged between components. In order to be able to adapt to different scenarios, it has undergone many researches. And after practice, the current shock absorbers have a variety of shock absorption methods. [0003] In the prior art, in order to adapt to different shock absorption methods and different impact directions, the structure of the shock absorber is often different. For example, in the shock absorption scheme of the bridge, the most common shock absorption method is the Corresponding shock-absorbing components are set at the seat position for shock-absorbing, and the sh...

[0003] In the prior art, in order to adapt to different shock absorption methods and different impact directions, the structure of the shock absorber is often different. For example, in the shock absorption scheme of the bridge, the most common shock absorption method is the Corresponding shock-absorbing components are set at the seat position for shock-absorbing, and the shock-absorbing components often achieve the purpose of shock-absorbing only by storing and releasing elastic potential energy. Although this shock-absorbing method can also achieve the effect of shock-absorbing , but it will release a secondary impact during shock absorption, which will cause the shock absorber to cause secondary damage to the shock absorption object during the shock absorption process, which will lead to poor shock absorption effect, so most of the current shock absorption The purpose of the device is to avoid the impact of the above problems on the shock-absorbing object

The use of hydraulic devices for buffering is an effective solution, but the combination of hydraulic buffers can achieve buffering effects, and because hydraulic buffers are difficult to maintain, when subjected to continuous and strong impacts, the durability of traditional hydraulic buffers Tried and tested, shock absorbers are susceptible to damage and not easy to repair
