中文摘要：

传统4层对称轧制限于设备能力无法轧制大厚度复合板,直接进行双层轧制实验成本太高。文中用大型商业动力学软件ANSYS/LS-DYNA模拟不锈钢/碳钢复合板异步轧制过程,确定压下率为15%时,异速比为1.08时,平直度可以达到30I以下。最终,根据这个模拟结果,指导不锈钢/碳钢复合板的轧制试验,可以得到不平度较好地轧制结果。用有限元模拟不锈钢/碳钢复合板非对称异步轧制结果,对类似的复合板轧制具有参考作用。

英文摘要：

Traditional 4 layer symmetrical rolling can＇ t rolling big thickness of composite panels limited to its equipment power, while double rolling experiments directly costs too much. In this paper, asymmetrical rolling of stainless steel clad plate was simulated in ANSYS/LS-DYNA. The flatness was detected below 30 when re- duction rate was 15% and different speed rate was 1.08. Based on this result, asymmetrical rolling experiment gained better plate flatness. It has reference function for similar rolling.
