故障树分析法(FTA)在大型飞机机载设备系统故障诊断中的应用

Application of Fault Tree Analysis(FTA) in Fault Diagnosis of Large Aircraft Airborne Equipment System

针对某大型飞机机载设备系统庞大、系统设备组成繁多、信号功能交联关系复杂、故障类型和故障点分散的特点,本文将根据故障树分析法(FTA)的应用原则和使用方法,对飞机机载设备系统故障进行定位和快速诊断,并结合实际案例,指出故障树分析法在大型飞机机载设备系统故障诊断过程中的具体应用方法和流程。

Aiming at the large-scale aircraft airborne equipment system,the complex system equipment,the complicated signal function cross-linking relationship,the fault type and the fault point dispersion,this paper will use the fault tree analysis method(FTA)application principle and usage method for the aircraft.The on-board equipment system faults are positioned and quickly diagnosed,and combined with actual cases,the specific application methods and procedures of the fault tree analysis method in the fault diagnosis process of large aircraft airborne equipment systems are pointed out.
