本文采用三维刚塑性有限元法对圆盘件的摆动辗压过程进行了数值模拟，针对具体算例进行了圆盘件摆辗中心变薄缺陷的预测，并且对所提出的缺陷防止办法进行了数值模拟，结果说明，采用有限元方法进行圆盘件摆动辗压工艺缺陷预报是可行的，所提出的工艺优化方案改善了工件的受力条件，避免了工件中心变薄的发生。 In this paper, the three-dimensional rigid-plastic finite element method is used to simulate the rolling process of the disc. The prediction of the thinning of the disc center is carried out for a specific example, and the proposed method of preventing the defects Numerical simulation results show that it is feasible to predict the defects of rolling and rolling of disc by using the finite element method. The proposed process optimization scheme improves the stress conditions of the workpiece and avoids the thinning of the workpiece center.
