AMESim Modeling and Simulation of Jet-pipe Servovalve

The structure and principle of 2-stage jet pipe electro-hydraulic flow control servovalve with mechanical feedback has been analyzed.Modelling a magnetic torque motor and a valve spool using basic library and component library of AMESim,Modelling an armature with flexure tube and feedback spring,a hydraulic amplifier using AMESet.The whole model of jet-pipe servovalve has been built,and the simulation results coincide with the actual situations.
