摘要
采用刚塑性有限元法 ,以实验结果为依据 ,以大型有限元软件ANSYS为分析工具 ,对双金属复合带材轧制过程进行计算机数值模拟。分析了双金属复合带材同步或异步轧制过程中 ,轧辊和轧件的应力、应变分布和轧件的塑性流动变形情况以及轧制力和力矩。以动画的方式模拟轧制过程 ,给出了一种预测轧制结果、减少实验时间和费用的有效方法。
A method to simulate the rolling process of bimetal composite sheets was given. Based on rigid plastic finite element method, in terms of experiment results, and by the means of FEM software ANSYS, the deformations, stresses, strains, plastic flowing in sheets, rolling forces and rolling moments in symmetrical or asymmetrical rolling of bimetal composite sheets were analyzed. The results above were expressed in computer animated way. An effective approach to predict rolling results and to reduce test time and test cost is provided.
