摘要: 现存的理论FLD误差过大、实验FLD制作繁忙,都不便于生产。本文经过理论分析给出确定FLD的新方法,经实验证明其结果与现有实验FLD基本一致,实验工作量明显减少。

Abstract: Theoretical Forming Limit Diagram (FLD) available has too much error, and experimental FLD determination is quite difficult, neither could be applied to production easily. To solve this problem, on the basis of theoretical analysis, a new method to determine the FLD is given. Experiment indicates that the result is almost the same as the expert mental FLD, at the same time, experimental work is much decreased.
