基于ANSYS/LS-DYNA66自冲铆接铆打腿部尖端几何参数的优化

摘要

In recent years , self- piercing riveting technology is brought into public attentian. In this paper, the parameters of the leg of the rivet were studies by using 2D with the finite element model, ANSYS/LS-DYNA, and their aptimized valueswere obtained.%近年来,自冲铆接作为一种新工艺越来越受到重视和青睐.本文利用大型有限元分析软件ANSYS/ LS-DYNA建立的自冲铆接的二维有限元模型进行分析,对铆钉腿部尖端几何参数进行优化,得出了其最优的几何参数.
