Multiform mechanical vibration damper

Abstract

The invention provides a multiform mechanical vibration damper. The multiform mechanical vibration damper comprises a torsional vibration vibration-absorption mounting flange, a four-leg chuck, an upper box body, a sector-shaped piston, a linear vibration vibration-absorption mounting rod and a lower box body, wherein the sector-shaped piston is mounted in the upper box body and the lower box body; the upper box body is fixedly connected with the lower box body; the torsional vibration vibration-absorption mounting flange is mounted on the four-leg chuck; the linear vibration vibration-absorption mounting rod is mounted on the sector-shaped piston by the lower box body; the four-leg chuck is mounted in the sector-shaped piston and penetrates through the linear vibration vibration-absorption mounting rod. The multiform mechanical vibration damper realizes the vibration-absorption effects of two vibration forms including linear vibration and torsional vibration, and has the advantages of simple structure, high energy absorption efficiency, wide application range, strong flexibility, convenience for installation and the like.

Description

technical field [0001] The invention relates to a damper, in particular to a multi-form mechanical vibration damper. Background technique [0002] US6615959B2 discloses a high-dissipation damper, which is composed of the following parts: a piston rod-piston assembly slidingly assembled in an oil cylinder, two working chambers containing hydraulic oil distributed on both sides of the piston, and the working chamber and the auxiliary chamber are continuous Connected. The auxiliary cavity contains an inhomogeneous energy absorbing-dissipating structure composed of hydrophobic microporous channels-porous matrix and associated liquid. In addition, the two working chambers and a common compensation chamber communicate through the relevant valve system, which contains a one-way valve, which can ensure that the relevant working chamber is automatically closed during the compression process and automatically closed during the stretching process. open. [0003] Although the damper ...

AI Technical Summary

Problems solved by technology

[0003] Although the damper has efficient energy dissipation and absorption, it also has the following defects: first, the linear reciprocating piston contained in it can only achieve linear vibration damping, and can do nothing for torsional vibration; second, in the The application requires a long installation space

[0005] Although the damper has the advantages of simple structure and adjustable resistance, it also has the following disadvantages: first, its damping fluid is viscous, the energy absorption effect is not good and there is leakage, and vibration energy cannot be efficiently eliminated; second , can only achieve the vibration reduction of torsional vibration, and can't do anything for linear vibration
