Numerical Simulation on Spherical-bottomed Cylindrical Drawing Parts Based on Process Parameters

对球底圆筒形零件在成形过程的受力进行了分析,得到了各个部位的应力状态。以非线性有限元分析软件Dynaform为平台,模拟了不同工艺参数条件下球底圆筒形零件的成形过程,得出了工艺参数对球底圆筒形件成形极限的影响规律。

The stress of spherical-bottomed cylindrical drawing parts in the forming process were analyzed,the stress state of all parts were received.The forming process for the parts was simulated based on non-linear finite element software Dyanform.The effect of different process parameters on the forming of spherical-bottomed cylindrical parts was obtained.
