摘　　要：建立了某款电动汽车车身骨架的几何模型,运用有限元软件Hypermesh在已建立的几何模型的基础上进行网格化,根据实际情况定义边界条件与施加载荷,完成有限元模型的建立;分析计算在相应载荷与边界条件下车身骨架的静态刚度、强度,并进行模态分析;最后提出优化的研究方案和具体实现方法,为车身骨架的改进优化提供了理论依据.The frame geometry model of an electric vehicle is built and meshed by using the finite element software Hypermesh. The loads and boundary conditions according to the actual situation are applied to complete the finite element model. The author also analyzes and calculates the static stiffness and strength of the frame in the corresponding loads and boundary conditions. The optimized research plan and specific method are proposed to provide the theory basis for the improvement and optimization of the body frame.
