摘要
利用概率论方法建立了应变疲劳强度概率分布与应变疲劳寿命概率分布之间的数学关系式，并根据应变－寿命转换关系，由已知的给定应变水平下的疲劳寿命概率分布求出给定寿命下的应变疲劳强度分布函数，便于进行可靠性分析。
In this paper,the mathematical relation between strain fatigue strength probability-law distribu- tion and fatigue life probability-law distribution is theoretically established by using a probabilistic method. According to the inverting relationship between strain and life a probabilistic density function of strain fa- tigue strength at a prescribed life is derived from that of fatigue life at a given strain level so as to facilitate the strain fatigue reliability analysis.
