| 摘 要： | 成形极限图通常是通过钢模胀形试验测得，实际测量的成形极限图与ASAME自动应变测试分析系统模拟计算的成形极限曲线吻合较好。应用成形极限图分析冲压零件成形的安全裕度和进行选材预测时，对以平面应变和胀形为主的成形零件具有较高的可信度，而对以深拉延变形为主的成形零件可信度不高。

| Abstract: | FLD is usually measured with swell test in rigid die. The tested FLD is good fit that one measured by analogue computer in ASAME(Automated Strain Analysis and Measure Environment). When application FLD for analyzing the safety of formed parts and the selection of materials, the result is quite reliable where the deformation is mainly plane strain and swell, but unreliable for deep drawing parts. |
