摘要
阐述了模态分析基础,完成了虚拟环境中车身的模态分析。通过对车身的模态分析,获得了车身结构固有的振动特性,并找出了车身结构在动态激励时的薄弱环节。对车身结构的改进具有指导意义。
In this paper,the basis of modal analysis was expounded.The model analysis of car body are made in ANSYS.By the results of modal analysis of the car body,the body′s natural dynamic features are got and located some weakness of the structure.It has positive impacts on the improvement of bus body design.
