摘　　要：针对机载设备在实际维修中多为基本修复,其故障样本修复前后相关的特点,考虑到基本修复设备故障发生过程呈现出非齐次特性,和传统的使用指数分布对独立故障数据进行建模的方法不同,论文基于历次故障数据相关联的特点,采用非齐次泊松过程(NHPP)对基本修复样本进行可靠性建模,并引入故障强度函数分析故障变化趋势。最后利用某机载设备实际的使用故障数据,将所提方法与传统指数分布建模方法进行仿真对比,验证了所提方法更好地拟合了故障数据,更贴近实际。In this paper,accounting for the inhomogeneous feature caused by the correlation between failure samples of basi⁃cally repaired equipment,a model for assessing the operational reliability of aircraft equipment based on the NHPP is proposed,which is different from the traditional modeling method using exponential distribution.At the same time,the concept of failure inten⁃sity is introduced to analyse the failure variation trend.Finally,the simulation contrast of the traditional method and the proposed method is conducted by applying the failure data of some equipment,which illustrates that the proposed method can better fit the pratical failure data than the traditional method.
