预测与健康管理(PHM)是近年来在军用装备研制中提出的一种新的保障技术手段.机载导弹发射装置作为机载武器系统的配套产品,已纳入飞机PHM 系统设计中.本文介绍了PHM的基本概念和关键技术,并根据发射装置的功能特点,提出了在线和离线相结合的发射装置PHM框架结构,最后探讨了实施PHM部位原则、监测参数的选取以及故障预测和维护管理方法.%Prognostics and health management(PHM) is a new maintenance technical means in mil-itary equipment development in recent years. As an auxiliary component of airborne weapon system, air-borne missile launcher has been considered in the design of aircraft PHM system. This paper introduces the basic concepts and key technologies of PHM, then according to the functional characteristics of the launcher, it presents a PHM frame structure which combines online and offline. Finally,it discusses the principle of PHM location, the selection of monitoring parameters and the methods of fault prediction and maintenance management.
