本文提出了一种解析/数值相结合的方法来求解描述金属带材在轧制过程中塑性变形的应力以及由此产生的轧辊压扁的方程。这给出了一个比标准数值格式更健壮、计算速度更快、精度相同的模型。最初，该模型假定弹性变形的轧辊在与带材接触时近似为圆弧辊型，但后来扩展到根据通过辊缝的压力辊型计算变形的辊型。这两个版本都适用于在线预测将金属带材轧制到给定厚度减薄量所需的轧制力。
Abstract A combined analytical/numerical solution method is developed to solve the equations that describe stresses in the plastic deformation of metal strip during rolling together with the resultant roll flattening. This gives a model that is more robust and computationally faster for the same accuracy than standard numerical schemes. Initially, the model assumes the elastically deformed rolls to be approximated by a circular arc profile when in contact with the strip, but it is later extended to calculate the deformed roll profile from the pressure profile through the roll gap. Both versions are suitable for on-line use in predicting the necessary roll force for the rolling of metal strip to a given thickness reduction.
