摘要
Abstract
The dynamic model of a double-stage nonlinear vibration isolation system with high-static and low-dynamic stiffness and inerter was established. Vibration transmission and dynamic characteristics of this model were analyzed using harmonic balance method. Then, influences of element parameters, including inertance of the inerter, pre-compression length and stiffness of the horizontal spring, damping coefficient, on the vibration isolation performance were discussed. Numerical results show that the inerter element can yield anti-resonance frequency and reduce the resonant frequency of the isolation system so that the system has lower isolation frequency bend and its low-frequency performance is improved. Meanwhile, the inerter is of positive significance for reducing the mass of the isolator and realizing the lightweight design of isolators. In addition, the nonlinear vibration isolation system also has better performance of vibration isolation than that of the corresponding linear one.关键词
