无人水下航行器故障预测与健康管理框架研究

Research on Prognostics and Health Management Framework of Unmanned Underwater Vehicle

摘要:

针对无人水下航行器维修保障难度大、成本高的问题，论述了 PHM 技术在无人水下航行器的系统级、分系统级、设备级的应用问题，提出了一套适用于无人水下航行器机载、岸基故障预测与健康管理(PHM) 系统框架结构。分析了其中的关键技术，在此基础上进行了无人水下航行器 PHM 数据流结构设计。最后，以 PHM 技术工程应用为线索，提出了无人水下航行器 PHM 总体集成技术方案。

Abstract:

Aiming at the difficulty and high cost of maintenance and repair of unmanned underwater vehicles， this paper discusses the application of PHM technology in terms of system，sub-system and equipment，and proposes a set of airborne and shore-based prognostics and health management(PHM)system framework structures. The key technology is analyzed，based on which the PHM data flow structure of unmanned underwater vehicle is designed. Using the engineering application of PHM technology as a clue，this paper ends up with proposing an overall integration technical scheme of unmanned underwater vehicle PHM.
