摘　　要：在试验研究的基础上,应用大型有限元分析软件ANSYS/LS-DYNA,采用弹塑性有限元法对Ag/Cu复合材料精轧过程进行有限元数值模拟,研究了压下量对轧件与轧辊间接触力、轧件变形等的影响,结果表明:合理的压下量对轧件端面形状的控制是有利的.对模拟计算与实验结果进行了对比,确定了模拟结果的准确性.在44%以下的压下量时,轧制压力相对稳定,有利于对轧件形状的控制.金属轧厚比对控制轧件厚度及形状、合理制定厚度比、节约复层的贵金属有重要的指导意义.Based on experimental analysis and with elastoplastic finite element method and FEM software ANSYS/LS-DYNA, finite element simulation analysis on finish rolling process of Ag/Cu composite is carried out, and the influence of percent reduction on contact force between sheet and rolls, sheet deformation, etc. is studied. The results indicate that reasonable reduction is favorable to control of sheet shape. Compared with results of experiment, simulation results are exactly right. Under reduction below 44% , rolling force is relatively stable, which is useful to control of sheet shape. Thickness ratio after rolling is of much significance to controlling thickness and shape, making thickness ratio reasonable, and saving precious metal
