| 摘 要： | 汽车排气系统同发动机和车体相连,为降低发动机工作过程对环境和乘员造成的影响,文章对排气系统进行了模态分析,并探讨了发动机的振动对汽车排气系统的影响,得出排气系统在各阶频率下的振型图。通过模态分析可知,发动机的激励频率对排气系统有一定影响,指出为避免排气系统发生共振,进行优化设计时,应使各阶的固有频率避开发动机的工作频率,改善排气系统的性能,延长使用寿命。

Modal Analysis of Automotive Exhaust System |
| |
| Abstract: | Exhaust system is linked to the engine and vehicle body, in order to reduce the influence to the environment and passengers in engine operating process, modal analysis of exhaust system is conducted, and the influence of exhaust system caused by engine vibration is analyzed. The vibration model graph in each frequency of exhaust system is gained. Excitation frequency of engine has influence on exhaust system according to modal analysis. It is indicated that in order to avoid resonance of exhaust system, nat... |
