飞机供电系统的改进型PHM方案
The Improved PHM Project Research on Power System of Aircraft
摘要
Abstract
The application of PHM can greatly help improve the dependability, the efficiency of maintenance, the advance of fault diagnosis and the capacity of fault tolerance of power system of More - Electric Aircraft. Since the traditional use of PHM in power system of More - Electric Aircraft is the concentrated project, in which the power system is looked as a segment system of aircraft function management area, the equipments have no PHM and the signals of the equipments are given to the PHM of function management district, which can not fulfill the needs of complicated power system. Based on analyzing the augmented -FMEA and sorting the faults, this paper designs a focus - distributing PHM system, adopts the augmented - FMEA and the prognosticating model of the fuzzy comprehensive evaluation and finally combines the power system PHM with the aircraft PHM properly. All the tasks done in this paper are of some practical value and thinking innovation, which decide the direction for the research and development of power system PHM.关键词
