摘　　要：PHM评价指标是装备健康管理系统设计输入与目标要求,也是对PHM系统进行验收核查的评价依据;目前国内航空主机所、科研院所与高校开展了大量的PHM技术研究和工程设计应用工作,但由于缺乏PHM系统指标体系的建立,导致研制方在PHM系统设计阶段难以明确功能性能要求,验证方在定型阶段缺乏统一的评价参考标准,使PHM系统的工程化进程缓慢;文章以典型机电系统为研究对象,通过剖析国外先进的PHM技术标准与规范文件,结合装备典型机电系统PHM系统的能力需求,从机电系统PHM的监测及诊断指标、预测指标、决策及评价指标三个维度分析和梳理PHM评价指标,建立了适用于装备设计与验证需求的机电系统PHM评价指标体系,解决了装备PHM系统设计中缺乏设计依据与验证评价指标的问题。PHM evaluation index is not only the design input and objective requirements of PHM system,but also the evaluation basis of PHM system acceptance and verification.Lots of PHM technology research and engineering design application work have been carried out in recent years.However,due to the lack of PHM system index system,,which makes the engineering process of PHM system slow.Taking the typical electromechanical system as the research object,this paper analyzes and combs the PHM evaluation index from the three dimensions of monitoring and diagnosis index,prediction index,decision-making and evaluation index by analyzing the foreign advanced PHM technical standards and specification documents and combining with the capability requirements of PHM system equipped with typical electromechanical system,The PHM evaluation index system of mechanical and electrical system is established to meet the requirements of equipment design and verification,which solves the problem of lack of design basis and verification evaluation index in equipment PHM system design.
