The mechanical configuration and work principle of the solenoid valve were described.The simulation model of the solenoid based on Ansoft and the entire simulation model of the solenoid valve based on AMESim were built.The simulation result of the Ansoft solenoid model was made use of in building the AMESim solenoid valve model.The couple simulation of electromagnetic circuit,mechanical components and hydraulic system was realized,the more precise dynamical characteristic simulation results of the solenoid were obtained.
