宽频吸振器设计及其刚度控制
Design of Vibration Absorbers in Broad Frequency Band and Their Stiffness Control Based on MRE
摘要
Abstract
The significance of research of semi-active vibration absorbers is introduced in view of the defects of narrow damping frequency band of the passive vibration absorbers. The ingredient and prescription of magneto rheological elastomer (MRE) are introduced. The magneto rheological effect is analyzed based on magnetic dipole theory. The semi-active vibration absorber is modeled and simulated by means of Matlab code to analyze the broadband vibration performance. The control method of eliminating resonance phenomenon of the control system caused by adding vibration absorber is proposed. Finally, the semi-active vibration absorber is designed with MRE elements and its broadband vibration reduction performance is demonstrated by experiment. The amplitude frequency characteristics of the control system are analyzed and the proposed control method is verified.关键词
