摘　　要：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 change of FLD and LDH of steel sheet under different lubricants is studied in this paper. It is shown that the lubricants have certain effects on the strain paths in the stamping process, no effects on FLD 0, and obvious effects on LDH 0.
