本文根据简化三维单元,建立了分析立轧非稳态过程的刚—粘塑性有限元列式,提出了产生初始速度场的新方法,成功地分析了铅块立轧非稳态过程,得到的结果与实验吻合较好。
In this paper, based on the simplified three-dimensional element, a rigid-viscoplastic finite element method for analyzing the unsteady state of stand-up rolling is established. A new method for generating initial velocity field is proposed. The unsteady state of lead stand- The result is in good agreement with the experiment.
