摘　　要：基于有限元和模态分析的基本理论,以半承载式客车车身为研究对象,建立以壳单元为基本单元的有限元分析模型。分析了车身弯曲刚度、扭转刚度和前六阶固有频率及振型,为车身的响应分析提供重要的模态参数,同时也为车身优化设计提供依据。Based on the basic theory of the finite element and modal analysis this paper takes the semi-integral bus body as object of study to set up its model and analyzes the body bending stiffness, torsional stiffness and first six natural frequencies and mode shapes. The important modal parameters are provided for the response analysis and the basis is given to the optimization design of the vehicle body.
