Reliability Data Analysis of Aviation Equipment Based on Weibull Distribution

The reliability data analysis is an important means to analyze equipment lifetime and failure, predict failure rules, study failure mechanisms and formulate maintenance strategies. This paper proposes a method of reliability data analysis for the aviation equipment based on Weibull probability distribution. The fault data of a certain type of equipment component collected in the quality control of aviation equipment is sorted out, and the Weibull distribution model fault data is used for statistical analysis. The mathematical model of Weibull distribution and the process of reliability data analysis are given, and its feasibility and practicability are verified by specific application examples. The specific method is used to determine the distribution type and test the goodness of fit by combining histogram and empirical distribution function. The maximum likelihood estimation method and hypothesis test are used to test the fault distribution and analyze the reliability lifetime characteristics.
