摘要

采用SORPAS软件对0.8mm DX52D+Z钢板与2.0mm 6111铝合金的自冲铆接过程进行数值模拟,分析铆接形成过程、应力应变以及载荷变化,模拟计算得出底切量和底部厚度分别为0.91 mm和0.23 mm。利用自冲铆接设备对上述材料进行实验研究,通过断面金相测量可知,底切量和底部厚度分别为0.83 mm和0.30 mm,验证了钢铝自冲铆接工艺过程仿真的有效性。

Abstract

The simulation of self piercing riveting process for 0.8 mm DX52 D+Z steel and 2.0 mm 6111 aluminum alloy is carried out by SORPAS software. Self piercing riveting process,distribution of stress and strain,and load stroke behavior are analyzed. The simulation results show that interlock distance and bottom thickness are 0.91 mm and 0.23 mm respectively. By self piercing riveting equipment,the experimental study of the above materials is carried out. Through the metallographic measurement of the section,the interlock distance and bottom thickness are 0.83 mm and 0.30 mm respectively,which verifies the effectiveness of the self piercing riveting process simulation.
