摘要 分析了传统可靠性模型的特点,指出传统的可靠性模型并不能很好地反映零件可靠度和失效率随载荷作用次数或时间变化的规律.采用泊松随机过程描述随机载荷的作用过程,综合运用应力-强度干涉模型、泊松随机过程以及概率微分方程建立了强度随时间退化时的零件动态可靠性模型.以强度退化服从指数规律为例,研究了零件可靠度和失效率随时间的变化规律.研究表明,零件的可靠度随时间逐渐降低;失效率曲线具有"浴盆"曲线的全部特征. The characteristics of the conventional reliability models are analyzed and it is found that they can＇t reflect well the relationship between the reliability and failure rate of components because it involves not only the time but also the frequency of random loading. The Poisson stochastic process is applied to describing the loading process to develop a time-dependent reliability model of components considering the strength deterioration with time passing, which is derived by the stress-strength interference model in combination with the probability differential equation. Taking the strength deterioration of components following the exponential rule as an example, how the reliability and the failure rate of components changes with time is studied. The result shows that the reliability of components decreases with time, and the failure rate curve of components presents all the features of the bathtub curve.
