As a typical servo hydraulic system,the high-speed switch solenoid valve actuators gradually become one of the most important parts in hydraulic system of high precision.The dynamic response characteristics of the high-speed switch solenoid valve with double reset springs were researched.Its multi-field coupling dynamic model was established.The influence of the spool inner diameter,spring stiffness,coil diameter,operating temperature,control frequency and duty cycle of the high-speed switch solenoid valve on the electromagnetic force and displacement of valve core movement was system researched.The optimal design parameters of the high-speed switch solenoid valve were gotten.It provide theoretical basis for further developing high-speed switch solenoid valve with fast response speed,stable performance,wider range of flow rate and pressure,strong adaptability to environment.
