摘　　要：通过有限(FEM)元速度场研究了冷轧铜铝双层板的复合过程,将该过程中金属的变形特征进行了分析,同时,将有限元计算结果与某工厂数据相结合,分析了轧制速度、压下率、异径同步、异径异步对铜铝双层板复合的影响。结果表明,速度场模型能够更有效地说明铜铝板的复合过程;轧制速度越大,变形区出口处复合面金属流动的同步性越差,复合强度越低;异径同步轧制铜铝复合板时,辊径比取1.4~1.6,变形区出口处复合面金属流动的同步性越好,复合强度较高;异径异步轧制铜铝复合板时,轧制速比取1.2,变形区出口处复合面金属流动的同步性越好,复合强度较高。The cold-rolled bonding process of copper/aluminum bimetal plate was investigated by the velocity field of finite element method（FEM）. At the same time, deformation characteristics of metal were analyzed in the bonding process. The study method was to combine theory calculation with field data. The circumferential velocity of rollers, rolling reduction rate, synchronous rolling of non-equal sized rollers and asymmetrical rolling of non-equal sized rollers were analyzed. Results show that the velocity field can explain the cold-rolled bonding process of copper/aluminum bimetal plate more effectively; the synchronicity of metal flow on bonding surface decreases with the increase of circumferential velocity about rollers near the exit of deformation area, and the bonding strength is reduced; in the process of synchronous rolling about non-equal sized rollers, diameter ratio of the rolls is 1.4~1.6 with a great synchronicity of metal flow near the exit of deformation area and a high bonding strength; in the process of asymmetrical rolling about non-equal sized rollers, the circumferential velocity rate of rollers is 1.2 with a great synchronicity of metal flow near the exit of deformation area and a high bonding strength.
