| 摘 要： | 用模糊集合描述应力和强度,探讨了模糊变量与随机变量同时存在时的疲劳强度可靠性设计方法。提出了当隶属函数与概率密度函数都是连续函数时的可靠度计算公式,推导出几种不同分布的可靠度计算公式,同时对模糊可靠度与普通可靠度的意义及其区别加以分析。

| Abstract: | eliability design methodology of fatigue strength is discussed with stress and strength variables described by fuzzy sets when fuzzy variables and random variables exist simultaneously.Some formulas of determining reliability are deduced assuming that membership function and probability density function are continuous The significance and difference be- tween the ″fozzy reliability″and general reliability are analyzed. |

| Keywords: | fatigue(materials) fuzzy sets strength reliability analysis |
