| 摘 要： | 根据P－S－N曲线族方程，求出了在可靠度为P时的材料常数，并由疲劳寿命分布推导出疲劳强度分布，最后采用一维动态应力-强度干涉模型，研究了在随机循环载荷作用下的某硬铝合金的疲劳可靠性。

| Abstract: | In this paper, material constants with respect to reliability were solved according to P-Sa-Sm-N curve family equation, and fatigue strength distribution was derived from fatigue life distribution.Finally, the fatigue reliability of a a hard aluminum alloy under random cyclic load was studied by means ofone dimensional kinematic stress-strength interference model. |
