轧制过程宽展问题的有限单元法分析

The Analysis of Spread in Rolling by the Finite Element Method

摘要: 本文根据刚塑性有限单元法,采用20节点曲六面体等参单元对平辊轧制过程进行了分析。求得金属三维流动的速度场,以及在稳态轧制时轧件的外轮廓形状等,并与实验结果进行了比较。

Abstract: In this paper, according to the rigid-plastic finite element method we have analized the three dimenssional flow of metal in the rolling by 20 nodals curved hexahedron isoparametric element.The three dimenssional flow velocity fi-eed of metal in the rolling and the deformed Shape of workpiece in steady-state flow have been obtained. The results got from computation have compared with the experiments.
