摘要：

采用传统方法轧制Cu/Al层合板的过程中易出现翘曲变形，新型波纹辊轧制对改善其翘曲变形具有积极作用，为探究波纹辊辊形参数对轧制Cu/Al层合板的翘曲的影响规律，借助数值模拟方法，研究了轧辊波纹幅值与周期对轧制Cu/Al层合板翘曲的影响。结果表明：对于给定初始厚度的Cu/Al层合板，其翘曲曲率随着波纹幅值的增大先减小后增大，随着波纹周期的增大而增大，其中，波纹幅值为0.2 mm、波纹周期为π mm的波纹辊轧制的Cu/Al层合板的翘曲曲率最小。研究结果可为制备高板形质量的Cu/Al层合板提供技术参考。

Warpage deformation is prone to occur during the traditional rolling process of Cu/Al laminates, and the new corrugated roller rolling has a positive effect on improving the warpage deformation. Therefore, in order to explore the influence laws of corrugated roller profile parameters on the warpage of rolled Cu/Al laminates, with the help of numerical simulation method, the influences of corrugation amplitudes and period of roller on the warpage of rolled Cu/Al laminates were studied. The results show that for Cu/Al laminates with a given initial thickness, the warpage curvature first decreases and then increases with the increasing of corrugation amplitude, and increases with the increasing of corrugation period. When the corrugation amplitude of corrugated roller is 0.2 mm and the corrugation period is π mm, the Cu/Al laminate rolled has the smallest warpage curvature. The research results can provide technical reference for the preparation of Cu/Al laminates with high quality of plate shape.
