先进的故障预测与状态管理技术

Advanced Prognostics and Health Management Technology

美军为了建立适应于 2 1世纪高技术局部战争的自主式后勤保障系统 ,正在大力开发嵌入式诊断和预测技术 ,如JSF的预测与状态管理 (PHM)系统、陆军的嵌入式诊断和预测 (ED/EP)系统、海军的综合状态评估系统 (ICAS)等。其中 ,JSF的PHM具有三军通用性。本文概括介绍了PHM技术的内涵和原理、结构和功能、技术特点和技术关键及在美军型号中的应用。

In order to establish the autonomous logistics system adapting to the high-tech regional war in the 21 st century,the US military is making great efforts to develop embedded prognostics and diagnostics technologies,such as the prognoatics and health management(PHM) system for JSF,embedded prognostics and diagnostics system for the US army and the integrated condition assessment system(ICAS) for the US navy,etc.Of which,PHM for JSF has commonality among the three services.The connotation and principle of PHM technology are introduced,its structure and fuctions are described,the technology characteristics and criticals are summed and the applications and benefit in the US military are discussed.
