摘要
论文阐述了动力松弛法的基本原理 ,推导出它在中心差分动力显式算法中的应用列式 ,并将其用于带锥形凸缘的圆形杯拉深成形过程的数值模拟研究 ,获得了满意的结果。
Basic principles of the Dynamic Relaxation Method are described and the formulations in dynamic explicit algorithms with the Center Difference are presented in this paper. This method is applied to numerical simulation of sheet drawing processes of circular cup with conic flange, and the results are satisfactory.
