采用Dynaform软件以汽车连接板弯曲后的回弹规律为例进行了数值模拟,利用正交试验得出制件最小回弹的条件组合,并根据分析结果设计出模具。 Dynaform software is used to take the rebound law of automobile connecting plate as an example to conduct numerical simulation. The condition combination of minimum rebound of workpiece is obtained by orthogonal test, and the mold is designed according to the analysis result.
