摘要
本文报告了板材特征值之一的γ值(各向异性系数)对翻边成形性能影响的研究结果,提出了极限翻边系数应按公式K_c=1/((1+r)n+1)去预测,并强调K_c与r、n是一种非线性关系。
In this paper, the effect of γ(normal anisotropy) of sheet metal tharaetcristic paramcters on flanging formability is primely resee(?)hed, and that is pro(?)sed: the limiting flanging coeffcient can be forecasted a(?)ording to formula and that was emphasized there is a nonlinear relation between K_c and r, n.
