摘要
随着系统复杂性、综合化、智能化程度的不断增加,系统的"五性"和寿命周期费用问题越来越受到人们的重视;近10年来,综合的故障诊断、预测与健康管理(PHM)技术已经作为欧美等国提高复杂系统"五性"和降低系统寿命周期费用的关键使能技术L回顾了PHM技术的发展演变过程,重点介绍了PHM技术在国外军事、民用和学术研究领域的应用现状,并给出了PHM在F—35战斗机上的典型应用案例,最后探讨了PHM技术的发展趋势。
As systems are getting more and more complex and integrated and intelligent, people pay more attention to their ＂ Five--A- bilities＂ （including Reliability, Maintainability, Testability, Supportability and Safety） and Life Cieyele Cost （LCC） problems. For recent ten years, integrated fault diagnostics, prognostics and health management （PHM） teehnologis have become the key enablers for foreign developed countries to improve complex system＂ ＂ Five--Abilities＂ and reduce their LCC, o This paper reviewed PHM＇s evolution process introduced their applications in foreign military, commercial and academic research ai-eas, in addition illustrated an typical ease about F--35 Joint Strike Fighter PHM system; and at last discussed some development trends about PHM technonogies.
