工艺对二次弯曲件起皱和料厚变化的影响研究

Study on process effects of wrinkling and variable material thickness of the two-bend part

建筑固定扣属于二次弯曲类零件。本文采用塑性有限元对不同工艺方案下的起皱和料厚变化进行了模拟分析 ,获得了抑制起皱的最佳工艺方案及合理工艺参数。

Architechural fastener belongs to two-bend part. In the article, the plastic finite element method is employed to simulate and to analysis the wrinkling and variable material thickness under different process schemes and to obtain the optimum process of restraining wrinkling and the reasonable process parameter
