摘　　要：带钢板形控制系统涉及轧制力和弯辊力影响系数,精确计算四辊轧机辊系轧制力和弯辊力影响系数的前提是获取轧制压力的分布函数和辊间压力的分布函数。研究了辊间压力与轧制压力的内在联系,采用力学原理建立了二阶辊间变形协调方程,结合三角序列级数实现了根据轧制压力分布函数对辊间压力分布函数进行耦合求解。其计算结果与生产实际参数的有限元模拟结果相比,具有很好的计算精度。Coefficient of rolling force and bending force is critical to shape control model in wide strip rolling process. Both the roll pressure distribution and gap pressure distribution are the preconditions of analytic solution procedure of deformation analysis in four high rolling mills. The relationship between the distribution of roll pressure and gap pressure is studied, after that a second-order coupled equation is established and the distribution of gap pressure and roll pressure is solved by using trigonometric series. The precision of the model is proved by the result of FEM.
