摘要
运用CAE仿真方法,研究排气系统上各个零部件对排气模态振型和频率的影响,分别得出影响振型及频率的关键部件,对前期如何控制排气振动和后期问题整改以及试验相关性分析具有重要指导意义。
Influence of component parts of the exhaust system on its modal shapes and frequencies is analyzed using CAE simulation method.Some key parts which have large influence on the modals and frequencies are found.This work may be helpful for vibration control,structure improvement and correlation analysis of exhaust systems.
