摘　　要：以汽车侧外板为研究对象,采用有限元技术对曲压料面的冲压成形过程进行了工艺分析。以结果作为模具结构力学分析的边界条件,对模具零件进行了有限元的变形和强度校核。通过冲压工艺参数的调整,得到了较为合理的工艺方案和模具结构。Taking the automobile sidewall panel as an example, the forming process with curved blank holder was analyzed by using finite element technique. Taking the results of the analysis as the boundary condition of die structure mechanics analysis, the deformation and strength of die components were checked with finite element method. Through adjustment of the stamping process parameters, a feasible process scheme and die structure were obtained.
