摘要

在无故障数据情况下,将失效概率结合Bayes理论引入置信限,分析了修正后的数据Weibull分布中单侧置信可靠性。其方法是:首先基于Weibull分布采用配分布曲线法进行分析,构造出多层先验分布给出失效概率的综合EBayes估计,结合最小二乘法拟合得到分布参数的估计值;根据参数的统计性质构造置信区间的枢轴量,同时,给出Weibull分布特征参数的区间估计和可靠度置信下限。以经典轴承试验为例,将此方法与其它方法计算结果进行对比,证明了该方法对置信可靠性评估的合理性和可行性。

Abstract

In the case of no-fault data,the failure probability combined with the Bayesian theory to study the confidence limit analysis to correct the unilateral confidence reliability evaluation. Based on the Weibull distribution,the distribution curve method was adopted to analyze,and the hierarchical priors distribution was constructed to give the comprehensive E-Bayes estimation of the failure probability,and the estimated value of distribution parameters were obtained by combining the least square method. According to the statistical property of the parameters,the pivot quantity of the confidence interval is constructed,and the interval estimation and reliability confidence lower limit of the Weibull distribution characteristic parameters are given.Taking the classical bearing test as an example,this method was compared with the calculation results of other methods,which proves the rationality and feasibility of this method in evaluating confidence reliability.
