为了快速计算六辊冷轧机辊系的弹性变形,提出了一种新的辊系弹性变形算法。该算法直接采用数值法计算轧辊挠曲,避免了复杂的公式推导,简化了计算过程;在辊系协调变形的迭代计算过程中,内层迭代首次引入辊间中心点处压扁和辊间压扁区倾斜两个迭代调节量,建立了与辊间接触合力和接触区的总力矩的联系,外层迭代通过不断修正辊间相对压扁量增量循环迭代辊间接触力与轧辊挠曲,实现了整个辊系变形的快速协调。通过与国外计算结果比较和算例的验证,证明其有好的计算精度、收敛性和快速性,能离线指导新轧机工艺方案设计,具备板形在线设定计算应用的可能。 In order to calculate the elastic deformation of the roller system of the six-high cold rolling mill quickly, a new roll deformation algorithm is proposed. The algorithm directly calculates the deflection of the roll by the numerical method, avoids the complicated formula derivation and simplifies the calculation process. During the iterative calculation of the coordinated deformation of the roll system, the inner layer iteration is introduced for the first time into the center point between the roll and the roll crush In the outer layer iteration, the contact force between the roller and the roller is iterated through incremental correction of the relative amount of crush between rollers, To achieve the entire roll deformation of the rapid coordination. Through the comparison with foreign calculation results and examples, it is proved that it has good calculation precision, convergence and rapidity. It can guide the design of new rolling mill process offline and has the possibility of calculating and setting the shape of on-line shape.
