Differential Drive Servo Valve based on MSMA

摘要：

　　Aimed at the contradiction between high frequency response and large flow of servo valve,the paper puts forward a 2D servo valve with differential drive based on magnetic controlled shape memory alloy(MSMA).To realize large flow control,the valve-spool is set of flow increasing orifice to match the flow increasing window on the valve-sleeve.The paper briefly introduces the structural features of the 2D servo valve and the working principle of the differential drive.It also has a simulation analysis on the magnetic field of the drive and the low field of the valve.Simulation results show that,the flow of the valve is linear with the input current.
