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。
FLD is measured usually by rigid die swell test, the FLD measured in real tests is in conformity with that got by analogue computing in ASAME(Automated Strain Analysis and Measure Environment); Analysis of punched parts' safety and precasting of selecting materials by using FLD,there's better reliability in the punched parts with plane strain and swell, and there's not good reliability in the punched parts by deep drawing.
