一、前言目前,平面变形时轧制压力的计算广泛采用下面的基本微分方程式,即:d(p_x-k)/(dx)-k/y·(dy)/(dx)±(t_x)/y=0式中:k=2K=1.15σ_uσ_u——该变形条件下的真实流动极限。
I. INTRODUCTION At present, the following basic differential equations are widely used in the calculation of rolling pressure during plane deformation: d (p_x-k) / (dx) -k / y.dy / dx ± t_x / y = 0 where: k = 2K = 1.15σ_uσ_u - the true flow limit under this deformation condition.
