摘要
将疲劳损伤累积过程看作是能量耗散的不可逆过程，从随机过程的角度，研究了各类随机损伤累积法则均应满足的若干必要条件，对目前已有的一些概率型疲劳损伤累积法则的统计相容性进行了较为系统的理论分析，建立了一类不依赖于疲劳寿命具体分布形式的随机疲劳累积损伤可靠性分析模型．
The cumulative process of fatigue damage is taken as a irreversible course of energy dissipation. from a standpoint of stochastic process, some necessary conditions which should be needed by any type of rational random damage cumulative rule is given for the first time. a systematic theoretical analysis of statistical consistency is made on existing probabilistic cumulative damage rules, and a class of reliability analysis model of fatigue cumulative damage.which depends on no given distribution of fatigue life, is established.
