摘要
在随机应力作用下强度随使用时间不断退化时,给出了一个周期性随机应力-退化强度干涉可靠性模型及其点估计方法,该模型考虑了应力与强度退化的相关性,最后利用算例验证了该模型的有效性.
A stress-strength interference （SSI） reliability model taking into consideration stochastic stress and strength aging degradation and point estimation of unknown parameters in the model are presented. Dependence of strength aging degradation on stochastic stress level is included into the models. An example is given to show the effectiveness of the method.
