摘要/Abstract

摘要： 为数值模拟分析时有效地预测树脂复合减振钢板成形过程中的失效形式，设计了测量两表层钢板之间法向黏结强度的试验方法，获得了树脂复合减振钢板的法向黏结强度；并设计了测试树脂复合减振钢板扩孔成形性能的试验模具，获得了极限扩孔率.试验结果表明：树脂复合减振钢板和单层钢板的差异在于成形性能参数和工艺参数不同；要将复合减振钢板成功地应用于工业生产中，必须针对复合减振钢板的变形特点而设定新的失效评判标准，并开发新的检验手段.

Abstract: The failure of LVDSS (laminated vibration damping steel sheet) is different from single steel sheet because of structural particularity. The delimination of interface and fracture of skin sheets are the common failure of LVDSS. The experimental method and the specimen were designed to test the normal bonding strength between the skin sheets of LVDSS. Furthermore, hole expanding experiments of LVDSS were also conducted. The normal bonding strength and the average hole expanding ratio were obtained, which provide useful failure criterion for numerical simulation. The experiment indicates that the difference between LVDSS and single steel sheet is not only the difference of material property parameters and process parameters but also the difference of failure mode. New failure criterion and examining approaches should be developed for the wide and successful application of LVDSS.

Key words: laminated vibration damping steel sheet, normal bonding strength, hole expanding capability
