摘要
排气系统吊钩的动刚度直接影响该处隔振系统的隔振效果,对车辆的NVH特性有重要影响。利用有限元方法对某正在开发的客车排气管被动侧吊钩进行了Mobility分析,结果表明设计方案满足设计要求。
The dynamic stiffness of the hanger directly influences the vibration isolation effect of the exhaust system, and has an important effect on vehicle NVH characteristics. In this paper, finite element method was used to analyze the Mobility of exhaust system＇s hanger; the results show that the design meets the design requirements.
