Abstract: The solenoid valve’s physical model is built based on Ansoft to gain interdependence of some variables in electromagnetic field. The simulation result of the Ansoft is led into the AMESim system model to realize the coupled simulation of electromagnetic structure, hydraulic system and mechanical movement. For the double seat solenoid valve, more accurate simulation analysis results of load characteristics, such as load response time and mass flow rate can be obtained.

Key words: double seat solenoid valve, coupled simulation, load characteristic
