Research on Prognostics and Health Management System for Self-Propelled Gun

摘要

Considering the encapsulation,tremendous working stress,complicated fault mechanism and process,an object-oriented architecture Prognostics and Health Management (PHM) system of Self-Propelled Gun is put forward to solve the difficulties in modem equipments' maintenance decision and safeguard.The relative key techniques,such as fault characteristics extraction,system identification,data fusion among sensors,adaptive fault thresholds setting,intelligent fault inference mechanism and fault prediction mechanism are discussed in detail.Above functional modules compose the PHM system.Their mutual relationships and data flow are shown as architecture graph,which is the basis of PHM system establishment.Simulation verification experiments indicate that the proposed architecture can satisfy the requirements of standardization,hierarchy and evolvement,as well as reducing the maintenance cost and difficulties.
