摘要： 文中推导了与Avitzur不同的运动许可速度场与应变速率场,经变上限积分与参变量积分未经数学简化获得轧制功率的上界理论解.该解与Avitzur按圆柱坐标系的解析结果作了比较.

Abstract: The two-dimensional velocity and strain rate fields which are different from Avitzur's have been deduced in this paper. An analytical upper-bound power to strip rolling has been obtained by using the integral as a function of the upper limit and the integration which depends on a, parameter without any mathematical ^simplification. The solution is compared with Avitzur's cylindrical coordinate solution.

Key words: strip rolling, continuous velocity field, analytical solution
