故障树分析法在某型飞机火控系统故障诊断中的应用

Application of fault tree analysis to fire control system fault diagnosis of one plane

故障树分析法是系统安全、可靠性分析研究中常用的一种方法。基于故障树分析法与专家系统相结合的某型飞机火控系统故障诊断仪,以机载火控系统不工作为顶事件,建立了故障树,并对故障树作了定性分析,本系统不但具有故障诊断能力,还具有较强的自学习的功能。结果表明,故障树分析法是机载火控系统故障诊断的一种有效方法。

Fault Tree Analysis is a common method in use of study on system safe and reliability analyze. Fire control system Fault diagnosis test instrument of one airplane base on Fault Tree Analysis combine with expert system build Fault Tree serve fire control system don＇t working as top matter, and make a qualitative analysis of Fault Tree.The system can implement fault diagnosis as well as self-learning. Use make known Fault Tree Analysis is an effective means of airborne weaponry fire control system Fault diagnosis test instrument.
