drawing and shaping die

A new comprehensive computer model was developed for sheet metal deep-drawing process, based on the theory of plastic anisotropy and under consideration of the effects of bending, blank-holding force, strain-hardening, the variation of thickness and tooling geometry.

建立了全面的金属薄板拉延成形过程塑性各向异性分析计算机通用模型；综合考虑了弯曲、摩擦、压边力、应变强化、板厚变化和模具几何性的影响，能用于动态模拟拉延成形过程；给出成形件应力、应变分布的连续变化曲线。

The stress-strain relations of studied materials in uniaxial and biaxial tension were also used to analyse and calculate sheet metal deep-drawing process and its forming parameters.

本文对金属薄板在单向拉伸和双向拉伸状态下的应力应变关系进行了理论和实验研究，给出了两种应力状态下所得ｎ值的相关性，分析了其预报成形极限的适用性，将研究材料在单向及双向拉伸试验中所获应力应变关系用于拉延成形的过程分析和极限成形参数计算，结果表明，单向拉伸时的应力应变关系用分析拉延成形过程更为符合实验结果。
