摘要
提出了基于失效模式影响及危害性分析(FMECA)、故障树分析(FTA)和历史案例的健康表征参数选取原则和方法,探讨了基于隐马尔可夫模型(HMM)和贝叶斯的健康表征方法及其应用。结合机载航电系统综合化射频信道架构,通过建立的模型对射频信道的健康影响进行了初步分析,得到了射频信道健康表征的优先参量。基于射频信道的健康表征参量和影响评估方法的研究对促进开展先进战斗机健康管理技术研究具有重要意义。
This paper proposes the principles and methods for selecting the health characterization parameters based on Failure Mode, Effects and Criticality Analysis(FMECA), Fault Tree Analysis(FFA) and historical cas- es. At the same time, it discusses the method and application of the health characterization parameters based on Hidden Markov Model(HMM) and Bayes. Considering the integrated RF channel architecture in airborne avion- ic system, this paper analyzes the health influence on RF channel by means of the built model and selected characterization parameters. The results are important for the technology research of advanced fighter health management.
