摘　　要：利用钣金成形软件PAM-STAMP对弯头进行冲压成形模拟,观察后处理结果,最大最小厚度分别为10.22mm和8.63mm,最大主应力及最大回弹分别为0.25GPa和10.05mm。与实际加工对比,分析了误差原因。最终验证了软件分析结果的准确性,为PF的馈线系统中众多的弯头提供一种可行的加工方案。The sheet metal forming software PAM-STAMP is used for stamping shaping simulation of elbow, then observe post-processing results. Respectively, the maximum and minimum thicknesses are 10.22mm and 8.63mm, the maximum principal stress and maximum Springbrook are 0.25GPa and 10.05mm. We can take it for comparison with the actual processing and analyze the reasons causing the errors. Finally it is verified that the results simulated by the software are accurate. It also provides a feasible processing solution for a large number of elbows of PF feeder system.
