| 摘 要： | 开发出二维非稳态刚粘塑性有限元计算软件ＲＶＰＦＥＭ，分析了火车车轮锻造中预锻和终锻两个工步的成形过程，给出各主要变形场量的分布。并实现成形过程数值模拟的屏幕动态显示。在搞清车轮成形过程金属流动规律的基础上，优选工艺参数和模具结构，研究出火车车轮成形的最佳工艺流程。

| Abstract: | A two dimensional rigid--viscoplastic FEM program (RVPEFM) for unsteady metal forming was developed. Optimal forming processes of railroad wheel including pre forming and finishing forming were simulated. The flow patterns of metal deformation were presented. Dynamic screen displaying which simulated forming processes was also accomplished. |
