铝合金AA5182-O自冲摩擦铆焊与自冲铆接工艺比较研究
A Comparative Study of Friction Self-Piercing Riveting and Self-Piercing Riveting of Aluminum Alloy AA5182-O
本文分别采用自冲铆接（SPR）和自冲摩擦铆焊（F-SPR）工艺连接铝合金AA5182-O。从接头宏观形貌、铆接力、显微硬度分布、准静态力学性能和疲劳性能等方面对两个工艺进行了系统比较。研究结果表明，FSPR工艺不仅在铆钉与板材之间形成了机械互锁，而且还实现了固相连接；而SPR工艺仅实现了机械互
锁。F-SPR 工艺在摩擦热软化的作用下，获得相同机械互锁所需的铆接力比SPR工艺降低了63%。随着F-SPR 模式转换深度的降低，铆钉周围铝合金加工硬化程度增加。当模式转换深度小于3.0 mm时，FSPR接头比SPR接头具有更高的铝合金硬度。F-SPR 接头中的固相连接和较高的铝合金硬度有效提升了接头的刚度和抗剪切能力，从而使接头的准静态拉剪强度和疲劳寿命与SPR接头相比均有显著提升。
In this paper, self-piercing riveting (SPR) and friction self-piercing riveting (F-SPR) processes were employed to join aluminum alloy AA5182-O sheets. Parallel studies were carried out to compare the two processes in terms of joint macrogeometry, tooling force, microhardness, quasi-static mechanical performance, and fatigue behavior. The results indicate that the F-SPR process formed both rivet-sheet interlocking and sheet-sheet solid-state bonding, whereas the SPR process only contained rivet-sheet interlocking. For the same rivet flaring, the F-SPR process required 63% less tooling force than the SPR process because of the softening effect of frictional heat and the lower rivet hardness of F-SPR. The decrease in the switch depth of the F-SPR resulted in more hardening of the aluminum alloy surrounding the rivet. The higher hardness of aluminum and formation of solid-state bonding enhanced the F-SPR joint stiffness under lap-shear loading, which contributed to the higher quasi-static lap-shear strength and longer fatigue life compared to those of the SPR joints.
