基于Bayes方法的无失效数据寿命分布研究

On Bayesian Method for Life Distribution of Zero-failure Data

Bayes估计是对产品无失效数据进行分析的一种有效方法。对无失效数据,给出了失效概率的Bayes估计,并结合配分布曲线方法和Matlab软件给出了无失效数据时产品寿命分布类型的确定方法。最后,结合某型发动机的无失效数据进行了计算分析,从而得到该型发动机的寿命分布函数。

Bayesian estimation is a very effective method about the analysis of the product＇s zero-failure data.In the paper,Bayesian estimation of failure probability of zero-failure data were obtained,and combined with distribution curve method and the software of Matlab,the method to ascertain types of product＇s life distribution was given out according to zero-failure data.Finally,engine＇s life distribution function was obtained based on the calculation and analysis.
