本文以实心圆管坯二辊斜轧穿孔为例论述了采用大型非线性有限元分析软件MARC模拟热力耦合过程中碰到的若干问题及其解决方法。重点在于解决三维模型建立、边界条件、接触定义等方面遇到的实际问题 ,为研究同类问题提供了有价值的参考
In this paper, we take a case of two-roll oblique rolling of solid round tube blank as an example to discuss some problems encountered in the simulation of thermodynamic coupling by using MARC, a large non-linear finite element analysis software and its solution. The emphasis is on solving the practical problems encountered in the establishment of 3D models, boundary conditions and contact definitions, etc., which provide valuable references for studying similar problems
