摘　　要：树脂复合减振板由两层钢板中间夹树脂层构成的,能起到减振降噪的效果。针对减振板的冲压成形过程中出现的起皱、破裂及脱层、表层滑移等缺陷,通过法向极限位移试验及切向极限位移试验建立减振板脱层的判据,通过经验公式建立成形极限的判据,并在此判据的基础上建立树脂复合减振板成形性判断系统,直观地反应减振板的脱层缺陷,并对U弯实验的脱层进行了验证。laminated steel sheet （LSS） sandwiched with polymer, is increasingly used for automotive, home ap- pliances, etc at present for it can improve product＇s vibration-damping and reduce noise without adding addi- tional weight. But in the process of forming, it will not only has the defects such as fracture, wrinkle, but also has the defects of delamination, skin sheet slipping which will not occur in normal steel sheet. The judge to these defects will guide the forming of laminates steel sheet, what＇s more it will have great reference value for other composite material forming. In this paper, delamination criterion was built by tangential limit displace- ment experiment and normal limit displacement experiment, then developing the laminated steel sheet formabili- ty judgment system, in order to show the defects of delamination vividly then the U bending test was done to verify the criterion.
