基于有限元某轿车左前门的模态刚度分析

Mode and Stiffness Analysis of Car Door Based on FEM

建立左前车门的有限元分析模型,对车门在自由状态下进行模态分析;在一定工况下对车门的框架刚度分析;在一定工况下对车门进行腰线刚度的分析,通过通用的有限元分析软件HyperMesh进行分析,为结构设计选择及结构优化提供了理论依据.

A finite element model of the left front door of a car was set up to carry out the modal analysis using software HyperMesh.The finite frequency as well as vibration types was gained.Besides,the waist stiffness and frame stiffness analysis were also carried out,so as to provide theory basis for car door development in the future.
