本文首先建立了某汽车排气系统的有限元模型，然后利用排气系统的自由模态试验结果与仿真结果对比，验证了有限元模型的准确性。最后对排气系统进行静力学分析，得出排气系统的每个橡胶吊耳的受力和位移情况。基于整车设计及布置要求对排气吊耳刚度进行优化，得出满足整车要求的吊耳刚度。

First of all, the finite element model of exhaust system were built, and then, using the exhaust system of the free modal test results and simulation results in contrast, the accuracy of the finite element model are validated. Finally, the exhaust system statics analysis, obtains exhaust system each hanger stress and displacement condition. Based on the design and layout of exhaust hanger stiffness optimization, it is concluded that the hanger stiffness which are satisfied with vehicle requirements.
