Abstract

A magnetic flow variation damping type power-driven shock and vibration absorption device, comprising a linear electric motor having a straight guide, a straddle, a magnetic flow variation damping apparatus and a metal spring. The invention also discloses the process for mounting the device. The beneficial effect of the invention is, the active vibration damper possesses good non-linear damping vibration performance.

Description

(1) Technical field: [0001] The invention relates to a vibration damping device applied to building structures and mechanical equipment, in particular to a magneto-rheological fluid damping dynamic vibration absorber. (two) background technology: [0002] According to the traditional design idea of ​​vibration reduction, the damping of ordinary vibration reduction system should not be too large. If only from the viewpoint of resonance control, it is hoped to increase the damping value of the system to reduce the resonance transfer rate and limit the resonance amplitude. However, from the perspective of pure vibration reduction, the increase of the damping value will reduce the vibration reduction effect. In the usual design methods, one is to keep the resonant frequency of the system away from the excitation frequency as much as possible to obtain a good vibration reduction design effect; the other is when the excitation frequency is wide, the system resonant frequency cann...
