摘要
根据P-S-N曲线上疲劳寿命存活率和疲劳强度存活率的等同性原理,借助已知的给定载荷下疲劳寿命概率密度函数,计算出未知的给定寿命下疲劳强度概率密度函数,为进一步进行可靠性分析奠定基础。
In this paper, according to equi-principle between fatigue strength distribution and fatigul life distribution on the P-S-N curve, probability density function of fatigue strength at a pres ciribed life is theoretically established by means of probability density function of fatigue life at a given stress level so that reliability analysis can be sucesfully done at the base of the probability density function of fatigue strength.
