Active control of nonlinear vibration absorber based on synovial algorithm

摘要

In this paper, the dynamic characteristics of Duffing strong nonlinear vibration absorber system with additional hard spring is analysed qualitatively. Based on synovial variable structure algorithm, the active control system model of the nonlinear dynamic vibration absorber is designed, and the effectiveness of the control model is verified by elevant examples. It's found that with the additional hard spring Duffing strong nonlinear vibration absorber, the control effect of active absorption is superior to the passive absorber, so which has has important guiding significance to the design of actual engineering nonlinear vibration absorber.
