为了研究粘接剂对自冲铆接头性能的影响,分别以TA1-5052和TA1-Q215的单搭自冲铆接头及粘接-自冲铆复合接头为研究对象,采用剖面直观检测法分析接头成形质量,基于静力学试验研究各组接头的静力学性能及失效形式。结果表明:与自冲铆接头相比,复合接头的钉脚张开度和残余底厚值减小;粘接剂对TA1-5052单搭自冲铆接头失效形式无影响,但改变了TA1-Q215单搭自冲铆接头的失效形式;复合接头的静力学性能比自冲铆接头更优;相对于自冲铆接头,TA1-5052复合接头静失效载荷增加了17.5%,能量吸收值增加了13.3%;TA1-Q215复合接头静失效载荷增加了6.8%,能量吸收值增加了25.8%。
In order to study the impact of adhesive on the performance of self-piercing rivets, respectively, TA1-5052 and TA1-Q215 single take-from riveted joints and bonding - self-piercing riveted composite joints as the research object, Forming quality, based on static test study of each group of static mechanical properties and failure forms. The results show that compared with the self-piercing riveting joint, the splice opening and the residual thickness of the composite joint are reduced. The adhesive has no effect on the failure mode of the TA1-5052 self-piercing self-piercing riveting joint, but the change of the TA1-Q215 single Compared with the self-piercing riveting joint, the static load capacity of the TA1-5052 composite joint increased by 17.5% and the energy absorption value increased by 13.3% The static failure load of TA1-Q215 composite joint increased by 6.8% and the energy absorption value increased by 25.8%.
