中国航空机载设备寿命研究

 从可靠性系统工程理论和方法出发，总结了中国航空机载设备寿命研究，在理论上、工程实践和管理上的成果和经验，提出了机载设备定延寿技术的理论基础是寿命概念的转变、评估方法的研究和应用、失效判据的研究和分析。这反映了我国在航空机载设备耐久性理论研究的成果。同时还就４种定延寿方法加以论述，并总结了成功的可靠性管理经验。这些均体现了中国航空机载设备寿命研究的特点。

STUDYO THE USEFULLIFE OF AIRBORNE EQUIPMENT

Using the reliability engineering theory and methodology, the theoretical, practical;and managerial achievement and experience on the useful life study of airborne equipment are summarized . It is concluded that the key elements of the achievement attained on the durability of airborne equipment in China are the change of the concept of usefullife, development of on applicable evaluationmethod, and establishment of aproper failure criterion. In this paper, four methods of life evaluation and extension are discussed and successful experience of reliability management is summarized. All the mentioned content embodies the features of studying the useful life of airborne equipment in China.
