In response to the high requirements and poor consistency in the machining and assembly processes of the armature and spool of the direct acting high-speed solenoid valve,AMESim was used to establish a multi physics field coupling model for this electromagnetic valve,which includes electricity,magnetism,mechanics and gas.The impact and separation between the armature and the spool were considered,and the model was validated on a test bench.Then it was compared and analyzed with another structural form in which the moving iron core is"bound"to the valve spool.The results indicate that there are differences between the two types of solenoid valves in terms of dynamic response and key parameters that affect dynamic response.Under the same conditions,the overall dynamic response of the first structural form of electromagnetic valve is slightly poor,but its requirements for the processing and assembly process of the armature and spool are relatively low.
