摘要
航空机载复杂产品基本是可修产品 ,按其修复深度分为完全修复和基本修复 ,而实际维修中又多为基本修复。完全修复后可靠性样本可用不可修模型处理 ,而基本修复可靠性样本采用何种数学模型处理在实际工作中尚不多见。介绍了进行某型国产新机机载产品使用可靠性研究中使用的分析模型 ,重点讨论非齐次泊松过程建模与故障强度概念 ,并指出了模型应用的方法及实例 ,给出了课题评估结果。
Almost all complex aircraft products are repairable. They are, by the degree of repair, of two categories: complete repair and basic repair. In practice, most of them are basic repairs. A non repairable model is applicable to the reliability sampling for completely repaired products. But no practical model is available for reliability sampling of basically repaired products. This paper presents an analysis model for assessing the operational reliability of the airborne equipment on a new aircraft in China, with emphasis on the nonhomogeneous Poisson process (NHPP)modeling and the concept of failure intensity. Application methods and examples for this model are given, followed by the assessment results.
