多机种一体化故障预测与健康管理技术应用研究

Research on technology application of integrated fault prognostic and health management

基于故障预测与健康管理的自主式保障是新一代飞机和直升机设计的基本能力,是航空装备综合保障领域的重要变革。研究介绍了飞机PHM系统体系结构,划分出机载PHM系统和地面PHM系统,提出机载PHM系统采用分层智能推理机构,地面PHM系统宿驻在地面自主保障信息系统,并优化了PHM系统工作过程;根据现实与可能,提出了实用性的综合智能故障诊断方法和维修任务预测算法;从多机种一体化保障需要,提出了飞机多机种自主式保障设计关键技术和研究方向。

AL （autonomic logistics） based on PHM （prognostics and heahh management） is a basic capacity of the new generation airplane and helicopter, as well as an important revolution in the field of aviation equipment integrated logistic support. The structure of PHM system including on-board and off-line systems is introduced in this paper. The organization of intelligent hierarchy inference is adopted in on-board system. The off-line system is stationed in the ground AL information system. An utility method of intelligent fault diagnosis and an algorithm of maintenance task prediction are proposed. On the other hand, the key technology and research direction on the AL design of multi kind airplanes are put forward.
