摘要
针对飞机液压泵源系统高可靠性和维修保障性要求,根据液压泵源系统故障特点提出了飞机液压泵源预测与健康管理系统的体系结构总体方案,描述了泵源预测与健康管理系统体系结构各层的功能,并对机载液压泵源健康监测系统和地面维护管理系统关键技术进行了研究.基于数字信号处理器设计了机载液压泵源健康监测系统和地面维护管理数据库,给出了鲁棒、快速和智能的故障诊断算法,为典型液压泵源系统故障预测和后勤保障提供了有效的方法,实现了液压泵源系统预测与健康管理的功能.
With the requirement of high reliability and indemnificatory of on-board hydraulic power supply system, the general structure of prognostics and health management （PHM） of hydraulic power supply system based on its fault mechanism was presented, the function of every layer in PHM of hydraulic power supply was described, and the key technology of on-board PHM system and ground maintenance system was studied. Considering the rapid calculation requirement, the on-board PHM and ground database of maintenance based on digital signal processor was designed. Intelligent diagnosis algorithm and effective fault prognostics were realized. The correctness and validity of the structure of PHM of hydraulic power supply system were tested and verified though the experiments.
