| Abstract: | In this paper,the large structure analysing program MSAP was used in finite element dynamic analysis for a semi-integral car body. With the help of system analysing program CRAS. the experimental mode analysis of car body was carried out, and the results of finite element dynamic analysis were verified. By the dynamic analysis of the body, several problems lying in the body structure in respect of dynamic characteristics were found, and the corresponding improvement measures were put forward. All these would provide the basis for the optimization design of car body. |
