本文对文献[2]提出的常用张力微分方程不适应于动态过渡历程计算及其基本论点进行了分析论证,指出其论点是不成立的,证明了常用的张力微分方程适用于张力小于弹性限的全部连轧情况,计算误差仅产生于忽略(1+σ/E)项。对文献[2]的其它论点也进行了分析讨论。 张力微分方程的解析解不仅能清晰地描述连轧过程的物理本质,而且提高了连轧动态模拟计算精度和减少了计算量。常用张力微分方程与总张力平衡方程式联立,推导出适用于动态变规格和穿带过程的离散型张力公式:
An analysis and discussion were made of the evidence whether the conventional differential equation is proper to calculate the dynamic transition process. It has been proved that the equation is applicable to all continuous rolling conditions of tension less than the elastic limit, however, the error may only be introduced by the neglected term (1+σ/E). The analytical solution of the equation gives not only clarifying the physical nature of rolling practice but also improving the accuracy and amount of the dynamic analogue calculation. Combining the aforementioned conventional differential equation with the balance equation of total tension, a discrete tension formula is then derived for dynamic guage change and strip threading procedure.
