摘要
这种新方法将欧拉法与拉格朗日方法结合起来,简单高效。它基于中等描述水平,轧制件纵向上用欧拉坐标,厚度和宽度方向上用拉格朗日坐标,时间变量是独立的,排除在外,计算轧制件厚度和宽度方向上的实际位移时,采用的流线形积分变成了沿着纵向的简单的欧拉坐标一元积分。
This new method, simple but efficient, takes advantage of Eulerian method and Lagrangian method. It is based on an intermediate level of description, using Etderian coordinate in the longitudinal direction of the strip, whereas in the width and thickness direction Lagrangian coordinates are employed. The time is eliminated as an independent variable. The streamline integration employed for calculating the actual displacement fields of the strip in width and thickness direction turns out to be a simple one - dimensional integral along the Eulerian coordinate in the longitudinal direction.
