基于模糊GO法的闭环民航运输机防滞刹车系统可靠性分析

对于结构复杂的闭环系统,使用传统FTA方法分析其可靠性较为繁琐。模糊GO法是一种基于GO法并得到改进的系统可靠性计算方法,相比较于FTA方法,模糊GO法更具有逻辑观念,能更精确的表示闭环系统可靠性的不确定性。以模糊GO法为分析基础,结合状态枚举法(以下简称枚举法),对某型闭环民航运输机防滞刹车系统进行可靠性计算,计算结果与FTA计算结果相比较,表明模糊GO法更适用于闭环系统的可靠性分析,为闭环系统可靠性分析提供一种新的思路。

Reliability analysis of closed-loop aero-transport landing gear antiskid brake system based on Fuzzy GO methodology

For a closed-loop system with complex structure, it is cumbersome to analyze its reliability using the traditional FTA method.Fuzzy GO method is a system reliability calculation method based on GO method and improved. Compared with the FTA method, the fuzzy GO method is more logical,which can more accurately represent the uncertainty of the reliability of the closed-loop system.Based on the fuzzy GO method and the state enumeration method(Called enumeration below), the reliability calculation of a closed-loop antiskid brake system of civil aviation aircraft is carried out. The calculation results are compared with the FTA calculation results, which shows that the fuzzy GO method is more suitable for the reliability analysis of closed-loop systems. Provide a new idea for the reliability analysis of closed-loop systems..
