粘滞型二级隔振系统优化研究

Optimization Research on Two-Stage Vibration Isolation System with Viscous Damping

摘要

特种改制车发电机组通过二级隔振与车身相连，隔振不良导致了改制车会议室内的轰鸣声。本文首先通过建立粘滞型二级隔振系统模型，然后Matlab编写程序，分析了不同参数变化对于二级隔振系统隔振率的影响结果.通过问题实际情况制定相应改善方案。实施方案后二级隔振系统隔振率得到提升，降低了车身钣金振动，降低了会议室内轰鸣声，从而解决了集成车会议室轰鸣声问题。

Abstract

The generator motor of a integrated vehicle is connected to the body through secondary vibration isolation. while cause the booming noise in the meeting room of the integrated vehicle.In this paper, the model of the hysteretic damping secondary isolation system is establist, write the program by Matlab, analyze the influence of the different of the parameters to the vibration isolation rate of the two-stage vibration system. the optimization proposal project is maked according to the problem. After the implementation of the scheme, the vibration isolation rate of the two-stage vibration isolation system is improved to reduce the vibration of body sheet metal and the noise in the conference room, thus solving the problem of the noise in the conference room of the integrated vehicle.
