摘要
轴承的寿命分布是威布尔分布,在一次全时截尾寿命试验中20套轴承无一失效.本文应用多层Bayes方法获得可靠度的估计.在一类先验分布下,此种估计是稳健的.
The life distribution of bearing is Weibull distribution We have done life tecta censored at fixed time. The result is all zero-failure! This paper tries to seek the estimation of reliability R(t) by the hierarchical Bayesian analysis. The result shows the estimation of R(t) is robust.
