The research of passive vibration isolation system with broad frequency field

Abstract

A passive vibration isolator with broad frequency field (zero dynamic stiffness system) is designed in this paper, whose mathematics model is built applying a mathematics method. Then the static and dynamic analysis of the isolator is conducted with ADAMS software. The zero dynamic system is developed based on theoretic study and simulation analysis. Moreover, the experimental validation of modal and frequency field is acquired. The modal experiment shows that the natural frequency of the isolator has dropped from 11.715 Hz to 2.5421 Hz because of importing negative stiffness mechanism. The result of the frequency field experiment is that the isolator has a better vibration reduction effect between 3 and 100 Hz.
