摘要: 本文提出的数值分析计算平底杯形件压延成形问题的方法,解决了应力、应变分布变化曲线的不连续问题,并为分析其它复杂冲压成形工艺建立了基础。研究结果表明,计算杯形件压延的力和变形时,可用全量理论代替增量理论,以简化理论分析的复杂性。此外,本文也得出了材料的各向异性及弯曲因素的影响程度。

Abstract: This paper develops a new comprehensive numerical solution of the deep-drawing of the cylindrical cups with flat-nosed punch. It can be used to get a continuous distribution of stress and strain in the whole region, and can be applied as the basics to analyze other complex metal forming processes. It is concluded that the total strain theory can be used as a substitute for the incremental strain theory to analyze the force and deformation in the deep-drawing of the cylindrical cups in order to simplify the theoretical analysis. In addition, the amount of the effect of the bending and anisotropy is also obtained.
