摘要

研究简谐激励下有阻尼智能弹簧减振系统参数的一种设计方法,使系统能同时实现阻尼与刚度控制。首先,利用等效线性化方法得到系统频响特性的的解析解。然后,分析了系统参数对幅频特性的影响,得到如下结论:系统无粘性阻尼时,幅频特性曲线簇有一个公共点,有阻尼时公共点消失;影响系统幅频特性的主要参数为质量比、刚度比、阻尼比和控制参数;阻尼比和相对阻尼比影响系统实现完全耦合时所需作动力的大小。最后,根据参数分析的结论,确定系统参数的选用范围,并给出系统参数设计的方法和步骤。

Abstract

A design method for system parameters of smart spring system with linear viscous damping under harmonic excitation is presented, which can make the smart spring system implement both stiffness and damping control. First, the analytical solutions of frequency response characteristics of smart spring system were deduced by equivalent linear method. Then, the influence of system parameters on the amplitude frequency characteristics of system was analyzed. The results show that the amplitude frequency characteristic curve cluster has a common point for the smart spring system without viscous damping, but the common point will disappear for the system with damping. The main system parameters that affect the amplitude frequency characteristics of system are the mass ratio, stiffness ratio, damping ratio and control parameter. And the system parameters of which affect the size of required actuator force to make the two mass-spring systems become fully coupled are damping ratio and relative damping ratio. Based on the conclusions of foregoing parameter analysis, the selection scope of system parameters of smart spring system was determined and the steps of parameter design were proposed.
