椭圆盒拉深成形的数值模拟

Numerical Simulation of the Drawing process of the Elliptical Box-like Drawn Part

在板料的冲压成形过程中,应变硬化化指数n和厚向异性系数r是两个重要的材料力学参数.采用DYNAFORM软件通过对椭圆盒的拉深成形过程进行数值模拟,研究了应变硬化化指数n和厚向异性系数r对零件成形性能的影响.

Strain hardening index n and coefficient of normal anisotropy r are two important mechanics parameters of materials in the stamping process. By using program DYNAFORM to simulate the drawing process of the elliptical box-like drawn parts, effect on the formability of sheet metal parts of n and r was studied.
