| 目的 针对铝/钢两种金属性能差异大，轧制复合存在严重的变形不协调及结合强度低的问题，研究轧辊同径与异径及单辊驱动对复合板协调变形及结合强度的影响。方法 通过有限元二次开发进行模拟建模，并结合同步和异步轧制实验分析板翘曲机理。结果 与铝板接触的轧辊作为主驱动辊可使板变形更协调且结合强度更高，变形翘曲度为0.048，结合强度为34.2 MPa。结论 采用接触铝侧轧辊单侧驱动，双金属界面实现复合的位置更靠近轧辊出口，复合后的双金属界面间的剪应力和所受弯矩较小，制备的铝/钢复合板变形协调性更好，且结合强度更高。 |

| The work aims to study the influence of the same diameter and different diameter of the roll and the single roll drive on the coordinated deformation and the bonding strength of the composite plate, so as to solve the large difference in properties between aluminum and steel, the serious deformation incoordination and low bonding strength in rolling compound. Through secondary development of finite element modeling, the plate warpage mechanism was analyzed in combination with synchronous and asynchronous rolling experiment. The roller in contact with the aluminum plate as the main driving roller could make the plate deformation more coordinated. The bonding strength was higher. The deformation warpage was 0.048 and the bonding strength was 34.2 MPa. When the roll contacting the aluminum side is driven, the position of bimetal interface is closer to the exit of the roll. Moreover, the shear stress and bending moment between the composited bimetal interfaces are smaller. Aluminum/steel composite plate prepared by this method has better deformation coordination and higher bonding strength. |
