研究了不同润滑条件下钢板FLD和LDH的变化规律。研究结果表明 :润滑影响了钢板冲压成形过程中的应变路径 ,但对FLD0 没有影响 ;润滑对LDH0 影响显著。
The changes of FLD and LDH under different lubrication conditions were studied. The results show that lubrication affects the strain path during the stamping process, but has no effect on FLD0. Lubrication has a significant effect on LDH0.
