摘　　要：DP800双相钢是目前广泛应用于汽车制造的一种新型高强钢。本文主要研究了DP800钢板V形弯曲时,两个关键工艺参数(凸模圆角半径和弯曲角度)对试件回弹的影响。测量并求得了不同工艺参数时试件回弹角的大小,并以此为基础得到了较好的工艺参数以及回弹角的变化函数。DP800 dual-phase steel is a new type of high-strength steel widely used in automobile manufacturing.The effects of two key technological parameters(radius of the punch and the bending angle)on the springback of DP800 steel plate V-shaped bending were studied.The springback angle of the specimen with different process parameters was measured and calculated.Based on this,the better process parameters and the change function of the springback angle was obtained.
