Modeling and Fault Simulation Reserch on Agriculture Pilot Pressure Reducing Valve Based on AMESim
The working principle of pilot reducing valve used in agricultural machinery is described.The simulation model of pilot reducing valve is established by AMESim,and the its dynamic characteristics are analyzed under common failure conditions,such as main valve damping hole blockage,main valve spool stuck and pilot valve spring fatigue.The simulation results show that the AMESim software can simulate all kinds of fault responses of pilot valve in actual operation,which provides a new method and basis for diagnosing the faults of pilot valve and similar hydraulic components quickly with accuracy,greatly reducing the fault diagnosis time and improving the working efficiency of the whole machine.
