Analysis and Optimization of Magnetic Guide Parts of Solenoid Valve Based on Maxwell

The two-dimensional model of the solenoid valve was established by using the electromagnetic finite element analysis software Maxwell.The influence of the structure and material properties of the magnetic guide parts of the solenoid valve on the per?formance of the solenoid valve was studied.Through the static and dynamic simulation analysis of the core diameter,air gap,coil po?sition,material properties and other key parameters of the solenoid valve,the relationship between the travel and magnetic force under different parameters was calculated,and the optimized parameters were obtained through comparison.Under the premise of maintaining the same voltage input,when the stroke is 0,the electromagnetic force of the optimized solenoid valve model increases about twice,and the volume decreases by 5.2%.Compared with the original model,this model has the advantages of low energy consumption,low manufacturing cost,large electromagnetic force and fast response.
