| Abstract: | The vibration energy of the exhaust system causes the vibration of the vehicle and structural noise, which harms the performance of the vehicle, especially in the riding comfort of a passenger car. In this paper, the finite element models of the exhaust system were built using HyperWorks, and the free vibration modal parameter calculations were performed with the FEA model. The results can provide an important reference to the structure design of the vehicle exhaust system. |
