摘要
本文针对带孔圆筒形件的推导，通过模拟分析并结合实验提出了带预制孔板料成形极限拉深系数的计算新方法。运用新方法计算筒形件的极限拉深系数比现有的计算公式更为合理。
In this paper, we aim at cylindrical-cup of hole, through numerical simulation and experiment. It will put forward a new way to calculate the limit drawing ratio of hole-cup blank. The new way to calculate the LDR is more in reason than the old one.
