基于BB算法的左截断威布尔分布可靠性分析
Reliability Analysis of Left-truncated Weibull Distribution Modified by BB Algorithm
摘要
Abstract
A reliability analysis was done based on the failure data of B737-800 main landing gear shock strut oil leakages herein,which came from a domestic airlines'electronic records,in considera-tion of the life distribution type and parameter estimation method.The characteristics of data prelimi-narily demonstrated that the life distribution type might be left-truncated two parameter Weibull dis-tribution,logarithmic normal distribution or exponential distribution.Next,the parameters corre-sponding to three types of distributions were estimated by using the MLE method.Then,the Kol-mogorov-Smirnov(K-S)hypothesis test,which modified by BB algorithm and goodness-of-fit test , was used to identify and confirm the life distribution function model.The analysis results show that the distribution of the data is left-truncated two parameter Weibull distribution.In the end,reasona-ble maintenance plan and optimized maintenance scheme are provided.关键词
