摘要
疲劳寿命概率分布的求取在疲劳可靠性设计中处于十分重要的地位。本文针对目前疲劳寿命概率分布的确定方法的不足,提出了运用模糊综合评判及贝叶斯理论综合考虑先验信息和小样本试验提供的信息来确定疲劳寿命分布的新方法。文中最后还运用具体算例进行了说明,表明了该方法的实用性与可靠性。
The seeking of probabilistic distribution for life-span of fatigue takes a very important position in 'the design of fatigue reliability. Aimed at the deficiency of the present determining method of probabilistic distribution for life-span of fatigue this paper put forward a new method of determining the distribution of fatigue fife-span by applying the fuzzy synthetical judgement, the priori information from the synthetical consideration of 贝叶斯's theory and the information supplied by small sample experi-rnents.Finally this paper carried out illustrations by the use of specific calculation sampie,this indicates the practicability and reliability of this method.
