本文的目的是证明二维 (2D) 任意拉格朗日欧拉 (ALE) 有限差分计算机代码可以准确预测电磁钣金冷却过程的动态。模拟由磁力加载的薄金属零件的变形的挑战性方面是求解高度耦合的偏微分方程组，材料运动和磁物理需要两个截然不同的时间步长来保持数值稳定性。 GALE 计算机代码有能力解决此类具有挑战性的问题。本文重点介绍了许多电磁钣金成形操作的 GALE 建模。 (C) 1998 年 Elsevier Science S.A. 出版
The intent of this paper is to show that a two-dimensional (2D) arbitrary Lagrangian Eulerian (ALE) finite-difference computer code can accurately predict the dynamics of the electromagnetic sheet metal funning process. The challenging aspect of simulating the deformation of thin metal parts which have been loaded by magnetic forces is solving a highly coupled system of partial differential equations, The material motion and the magnetic physics require two drastically different time steps to maintain numerical stability. The GALE computer code has the ability to solve such challenging problems. This paper highlights the GALE modeling of a number of electromagnetic sheet metal forming operations.
