本文针对抛物体形拉深件的液压成形工艺过程 ,采用大型非线性显式动态分析软件ETA/Dynaform3 0 ,通过数值模拟的方法进行了研究 ,实现了一步成形抛物体形拉深件。
In this paper, aiming at the hydroforming process of paraboloid drawing parts, a large-scale non-linear explicit dynamic analysis software ETA / Dynaform3 0 was adopted and the numerical simulation method was used to realize the one-step forming paraboloid drawing parts.
