摘要/Abstract

摘要：

采用Q195钢板和5A05-O铝板对自冲铆接、无铆钉铆接和电阻点焊3种连接工艺进行了试验，对各种连接接头进行了拉伸测试，并且分析其失效形式。试验结果表明:对于钢板与钢板的连接,
电阻点焊接头静强度大于自冲铆接和无铆钉铆接接头静强度;对于铝板与铝板的连接,
自冲铆接接头静强度大于电阻点焊和无铆钉铆接接头静强度。对于不同连接工艺，钢板与钢板之间的连接强度约是铝板与铝板之间的连接强度的2到4倍。

Abstract:

Self-piercing riveting,clinching and resistance spot welding were described by joining Q195 steel sheets and 5A05-O aluminum sheets respectively.The tensile tests and failure modes were also analyzed.The results show that the joint of resistance spot welding have higher static strength than the other two joints when steel sheets are joined;while the joint by self-piercing riveting have the best strength when aluminum sheets are joined.The joining strength of steel sheets is about 2~4 times larger than that of aluminum sheets for the same jointing technology. 

Key words: self-piercing riveting, clinching, resistance spot welding, strength analysis
