摘　　要：针对某型车架满载时车身产生严重弯曲变形的问题,在有限元法的基础上,利用ANSYS软件建立车架三维有限元分析模型,并进行变形和应力计算机仿真分析,结合变形实验,得到车架变形及应力变化规律,找出了车架产生严重弯曲变形的原因,并对大梁截面尺寸进行优化,提出优化改进方案。According to the severe bending deformation of a light truck frame with full load and finite element method, the paper sets up a three-dimensional finite element analysis model by using ANSYS software, and the deformation and stress analysis and computer sim- ulation combined with the deformation experiments, gets the rule of frame deformation and stress variation, finds out the reason for bending deformation of beam frame, section size optimization and the optimal scheme.
