摘要
故障树分析(FTA)是一种逻辑性强的系统安全性分析方法,被广泛应用于航空发动机故障的调查及危害性事件的定性、定量分析中。在阐述危害性事件应用FTA的必要性,以及简要介绍FTA方法(包括其原理、分析流程、分析要点等)的基础上,详细论述了FTA在某型航空发动机的典型危害性事件上的应用示例,对底事件、最小割集、采取的措施等进行了梳理和分析。该方法能有效识别关键故障模式和薄弱环节,有助于降低危害性事件发生概率,可有效支撑航空发动机安全性设计。
Fault Tree Analysis(FTA)is a highly logical analysis method for system safety that has been widely used in the investigation of aircraft engine faults and the qualitative and quantitative analysis of hazardous top events.On the basis of explaining the necessity of applying FTA to hazardous events and introducing the FTA method(its principles,analysis process,analysis points,etc.),this paper elaborates on the application examples of FTA in typical hazardous events concerning a certain type of aircraft engine,and sorts out and analyzes the bottom event,minimum cut set,and measures taken.This method may effectively identify key fault modes and weak links,helping reduce the probability of top events and effectively supporting the safety design of aircraft engines.
