Abstract: A new energy automobile enterprise uses high corrosion resistance steel S450AW to press the right door panel parts, and the height of the four corner convex is obviously low, which can not meet the product requirements. In order to solve practical production problems quickly, drawing and shaping analysis models are made according to product digital models. The simulation analysis of the whole process of right door panel stamping is completed by computer aided engineering (CAE) simulation, and the simulation analysis results are compared with the upper and lower die surfaces of the actual stamping die by the reverse scanning of the ATOS I 350 & TRITOP 3D optical mapper. The causes of stamping problems are determined and the mold optimization scheme is developed. The optimization scheme is implemented and stamping verification is carried out to solve the problem of insufficient height of the parts boss, which provides an alternative technical scheme for solving such problems in the future.

摘要： 某新能源汽车企业采用高耐蚀钢 S450AW 冲压右门板零件，出现四个拐角凸台高度明 显偏低的问题，无法满足产品要求。为快速解决生产实际问题，根据产品数模制作拉延及整 形分析模型，采用计算机辅助工程（CAE）模拟完成右车门板冲压全工序模拟分析，将仿真 分析结果与 ATOS I 350 & TRITOP 三维光学测绘仪逆向扫面实际冲压模具上下模的模面进行 对比研究，确定了冲压问题的产生原因并制定模具优化方案。实施优化方案并冲压验证，解 决零件凸台高度不足问题，为今后解决此类问题提供了可供选择的技术方案。
