This article focuses on the fatigue performance of thin aluminum plate SPR riveted joint. Through a series of physical tests on the fatigue performance of thin aluminum plate SPR joint, the fatigue life relationship under tensile and shear loads are obtained. Based on the Rupp theory and combined with simulation method, the stress range and fatigue life relationship under tension and shear loads are obtained. Nine parameters of Rupp constitutive model are optimized using Excel & Hyperstudy, and a normalized S-N curve for the fatigue life of thin aluminum plate SPR joint is constructed. The fatigue life prediction method for thin aluminum plate SPR joint is established, supporting the forward design of thin aluminum plate SPR joint structure.

为研究薄铝自冲铆接(SPR)接头疲劳性能,通过一系列薄铝板SPR接头的疲劳性能物理试验,获得了拉伸和剪切载荷下的载荷与寿命关系。基于Rupp理论,结合仿真方法分别得到拉伸和剪切下的应力范围与寿命关系,通过Excel和Hyperstudy对Rupp本构中9个参数进行优化,最终归一化拟合构建薄铝板SPR接头疲劳寿命的S-N曲线,建立了薄铝板SPR接头的疲劳寿命预测方法,支持了薄铝板SPR接头结构的正向设计。

为研究薄铝自冲铆接(SPR)接头疲劳性能,通过一系列薄铝板SPR接头的疲劳性能物理试验,获得了拉伸和剪切载荷下的载荷与寿命关系。基于Rupp理论,结合仿真方法分别得到拉伸和剪切下的应力范围与寿命关系,通过Excel和Hyperstudy对Rupp本构中9个参数进行优化,最终归一化拟合构建薄铝板SPR接头疲劳寿命的S-N曲线,建立了薄铝板SPR接头的疲劳寿命预测方法,支持了薄铝板SPR接头结构的正向设计。

This article focuses on the fatigue performance of thin aluminum plate SPR riveted joint. Through a series of physical tests on the fatigue performance of thin aluminum plate SPR joint, the fatigue life relationship under tensile and shear loads are obtained. Based on the Rupp theory and combined with simulation method, the stress range and fatigue life relationship under tension and shear loads are obtained. Nine parameters of Rupp constitutive model are optimized using Excel & Hyperstudy, and a normalized S-N curve for the fatigue life of thin aluminum plate SPR joint is constructed. The fatigue life prediction method for thin aluminum plate SPR joint is established, supporting the forward design of thin aluminum plate SPR joint structure.
