摘要：针对铁路货车门板更换新材料冲压时出现制件翘曲异常及4 个拐角凸槽高度偏低的问题，采用三维光学测绘仪扫描实际模具零件型面，应用有限元分析软件进行全工序成形模拟，将实际模具零件型面数据与成形的制件数据进行对比，找出产生问题的根本原因，并制定模具整改方案。实际验证表明：三维逆向扫描和有限元模拟相结合应用可以提高模具整改效率，节约制造成本，缩短整改周期。

Abstract: In view of the problem of warping and significantly lower height of four convex slots at four corners of part during the stamping of the wagon door panel after changingmaterial, the actual stamping die surface was scanned by using 3D optical mapping instrument, and the whole forming process was simulatedby finite element analysis software. The root cause of the problem was found out and the die optimization method was formulated after compared the actual die surface data with those of product design data. Practices verified that the combination of 3D reverse scanning and finite element simulation could effectively improve the efficiency of die rectification.
