摘 要: 针对Newton-Raphson迭代法存在难以实现轧制力和轧制功率负荷分配模式在线应用的缺陷,提出了一种变步长数值转换方法。模拟计算结果表明,该方法可满足计算要求,能实现上述2种负荷分配模式的在线应用。 The defects of Newton-Raphson algorithm was analyzed, which resulted in the rolling force mode and motor power mode of load distribution unable to on-line use, A new algorithm named variable step-length numerical conversion method was put forward. The simulation results show that the calculation requirement can be assured, and the on-line usage of two mode load distribution can be carried out.
