摘　　要：网格实验可以准确的反映材料在冷冲压成形中的应变状况,提示出成形中的危险区域,因此可以在冷冲压模具验收中发挥关键作用。以某款轿车侧围内板零件为例,通过网格实验明确了该零件在拉延成形中的开裂隐患位置,并从模具和材料两个方面提出了优化方案,取得了理想效果。Strain distribution of material in cold stamping forming could be detected accurately by means of grid string analyzing experiment so that crack-risk zone could be determined, thus playing a key role in acceptance of cold stamping die. Taking the side panel part in one bond of car as an example, this article specifies cracking potential locations in drawing process through the grid string analyzing experi- ment, offering optimization schemes from two aspects such as mold and material, achieving desired effect.
