【摘要】:对TA1钛合金板及与1420铝锂合金板(AL1420)、5052铝合金板(AA5052)、镀锌钢板(Q215)和铜合金板(H62)的异质T型自冲铆接头进行剥离试验,观察了各组接头的成形质量。分析了接头的力学性能和能量吸收值。结果表明:自冲铆接技术能够实现TA1异质板材的有效连接,其中TA1-Q215接头的最大剥离载荷高于其余3组接头,TA1-AL1420接头能量吸收性能最优。
[Abstract]:The peeling tests were carried out on TA1 titanium alloy sheet and heterogeneity T-type self-impact riveting head with 1420 Al-Li alloy sheet (AL1420) 5052 aluminum alloy plate (AA5052), galvanized steel plate (Q215) and copper alloy plate (H62). The forming quality of each joint was observed. The mechanical properties and energy absorption of the joints were analyzed. The results show that the self-punching riveting technique can realize the effective connection of TA1 heterogeneity plates, and the maximum peeling load of the TA1-Q215 joint is higher than that of the other three groups of joints. The energy absorption performance of the TA1-Q215 joint is better than that of the other three groups of joints.
