Some industries such as military industry and car industry require higher and higher dynamic characteristics in-dex of a solenoid valve.However, it is expensive and difficult to design and develop a fast and accurate test system of dynamic characteristics for solenoid valves.Prediction and evaluation of dynamic characteristics of solenoid valves by com-puter simulation are realized with finite element method in this paper. Firstly, a finite element simulation model of two-dimensional electromagnetic field of a solenoid valve is established by Ansoft Maxwell software.All kinds of dynam-ic characteristic curves can be obtained by calculating the dynamic response characteristics of the magnetic valve in the opening process, such as working current curve.Finally, the effect of different parameters, such as initial gap, driving voltage and turns per coil,on dynamic response characteristics is further studied in the opening process of the magnetic valve.The result shows the finite element simulation of dynamic characteristics of solenoid valves based on Maxwell can realize fast prediction of the dynamic characteristics in the opening process of solenoid valves.Besides,the finite element simulation can help to analyze and evaluate the dynamic response effect of each key design factor.
