Abstract:

Aiming at the technical bottleneck of the PHM system, which is difficult to be accurately designed, and to meet the requirements of improving the technical capability of aircraft fault diagnosis and health management. In this paper, based on a large number of research and reference to the domestic and foreign aircraft PHM system design experience, combined with the specific background of domestic PHM design. Through in-depth analysis and Research on the mechanical and electrical system of the aircraft, a new method for the PHM system of the aircraft mechanical and electrical system is proposed. In this paper, the design idea of the structure of mechanical and electrical system PHM and the design of the mechanical and electrical system PHM is presented. The aFMECA analysis of the mechanical and electrical system is carried out. The guiding ideology, function and composition of the system are defined, and the design scheme of the main functional modules is discussed. At last, the PHM technology scheme of the electromechanical system is formed, which has important function for promoting the development of PHM technology in China, and it has some guidance for the research of PHM technology.
