摘要
在中厚板轧制成形过程中采用有限元方法进行数值模拟分析可以为实际生产提供合理的工艺参数,便于延长轧机的寿命,提高产品质量和减少试错过程的消耗等。文中阐述了利用有限元软件对中厚板轧制成形过程的非线性数值模拟分析中的一些广为关心的问题,包括:摩擦力在轧件表面的分布情况以及摩擦力大小对轧制过程的影响;材料的等向强化模型、运动强化模型和混合强化模型对中厚板轧制过程的影响;热-力耦合对厚板轧制成形过程的影响及其数值模拟分析方法。
FEM numerical simulation is a useful tool to simulate the plate rolling process, it could help to extend the mill life, improve the quality of the plate and reduce the cost of trial-and-error processes. In this paper, some of the most concerned problems in numerical simulation of plate rolling process are analyzed and discussed using MSC marc software. The distribution of frictional force on the rolling plate surface and the effects of friction on rolling process are discussed. Different material hardening models such as isotropic hardening, kinematic hardening and combined hardening are investigated. The effects of thermal-mechanical couple on the plate rolling process and the numerical simulation method are presented.
