为分析带裙座整体封头的成形工艺 ,在商用有限元软件 ANSYS上二次开发了专用的封头成形分析模块。该模块根据封头的尺寸参数 ,采用参数化方法建立有限元模型。根据数值模拟结果 ,分析了封头成形缺陷的产生原因及坯料形状对成形过程的影响
In order to analyze the forming process of the whole head with skirts, a special head forming analysis module was developed on commercial finite element software ANSYS. The module based on the size of the head parameters, using parametric method to establish the finite element model. According to the numerical simulation results, the reason of forming defects of head and the influence of blank shape on the forming process are analyzed
