| 摘 要： | 指出疲劳应力的两类影响因素——横向和纵向因素,以区分疲劳应力的两类分布——横向分布和纵向分布。在不同影响因素作用下应采用不同的可靠度计算模型。提出了Miner定理-干涉模型综合法,该法可计算两类影响因素同时存在时的疲劳可靠度。

| Abstract: | To define the two different types of fatigue stress distribution. i. e. longitudinal and transverse, the authors put forward that there are two kinds of factors influencing fatigue stress: longitudinal and transverse. Different models should,therefore,be applied to reliability calculation if the influencing factors are of different kinds. A new model is proposed combining Miner's rule with the interference model,by which the fatigue reliability can be calculated in case both the two kinds of influencing factors come into effect. |
