Fault Diagnostic of Electro-hydraulic Servo Valve

摘要：

　　In order to achieve the fault diagnostic and degradation assessment of the electro-hydraulic servo valve,a system of prognostic and health management based on the data-driven approach for the electro-hydraulic servo valve is presented.FMMEA performed in this study considered the degree of sub-components in electro-hydraulic servo valve.In order to use only five parameters to assess the cause of degradation,a physical model of the EH servo valve was built up to simulate the failure modes.The simulation results are very useful because the methods can be applied to assess the cause of degradation such as leakage,jamming,clogging and so on.
