The Curvillinear Integral Problems to Velocity Field for Drawing Through Parabolic Dies

摘要: 文章采用von Kàrmàn基本假设对模面函数为抛物线(又称喇叭模)的拔制问题设定了运动许可速度场,并经曲线积分与变上限积分得到拔制力的上界解析解。

Abstract: In this paper with Von Karmani's basic assumptions a kinematically admissible continuous velocity field has been established to drawing through parabolic dies (or called trumpet dies). Then by using the curvilinear and the integral as a function of the upper limit an upper bound analytical solution of the drawing stress is obtained.
