摘　　要：对一大客车车架有限元计算方法进行了讨论 ,并辅以模态试验和强度刚度试验来校验有限元计算结果。详细论述了有限元建模技术和两种危险工况下加载等方面的关键技术 ,对此类客车车架的静态和动态分析有一定借鉴作用。In this study,the static and dynamic analysis of a city bus frame is performed with both the experimental method and the finite element method(FEM). Firstly,the FE model is built on the CAD model. Secondly,the dynamic analysis is performed to get the natural modes by FEA and experiment respectively. Finally,the FE model is used to calculate the stress and strain of the frame under two serious load cases. The method mentioned here may help the analysis of similar structure.
