摘　　要：利用ETA/Dynaform软件对QT8812发动机油底壳进行了二次拉深成形的回弹模拟分析。分别选取切边前,切边后的浅盒部分,并采集选取这些部位有代表性的特征部位的数据进行了分析比较。结果表明,二次拉深成形切边以后回弹量很小,绝对尺寸没有超过允许的2 mm。The springback of QT8812 engine oil-pan twice drawing forming was simulated by ETA/Dynaform software.Selecting the shallow box of before and after trimming respectively,gathering the typical characteristic data of these positions were analyzed and contrasted.The results show that the springback of twice drawing forming part after the trimming is very little,and its absolute size is less than allowable 2 mm.
