| 摘 要： | 指出了两类疲劳应力统计分布影响因素：横向统计分布影响因素和纵向统计分布影响因素。在不同应力统计分布影响因素作用下须采用不同的可靠度计算模型。提出了同时存在疲劳应力的两类统计分布影响因素时的可靠度计算模型：Ｍｉｎｅｒ定理－干涉模型综合法。使用该法计算了某构件在复杂载荷作用下的疲劳可靠度。

| Abstract: | This paper points out that there are two kisds of factor,transverse distributions influence factor and longitidinal distributions influence factor,effectisg fatigue stress distribution.Different reliability calculation model should be adopted when different influence factors exist.This paper presents a reliability calculation model,Synthetic method of Miner's rule and interference model,for the situation which both of the influence factors exist.An example is given for calculating the reliability of element under complex loads by using this method. |
