摘　　要：针对零件疲劳强度可靠性设计中数据不足的情况，根据现有的设计资料，借助于设计者的经验来判断与综合影响疲劳强度的诸多模糊因素，讨论了以模糊数来表示疲劳强度的方法。并利用模糊概率理论，计算了减速器输出轴的模糊可靠度。In view of short of data in reliablity design of fatigue strength of parts, this paper discusses the method which describles fatigue strength in fuzzy number by use of design data at hand, and by judging, synthesizing fuzzy factors which affect fatigue strength according to the experience of designers. And then, this paper calculates the fuzzy reliability of an output shaft of reducer according to the theory of fuzzy probability.
