The static characteristics of solenoid valve play an important role in the performance of brake system and can indirectly reflect the response speed of the brake system. The static characteristics of the solenoid valve reflect the electromagnetic characteristics of the solenoid valve itself, revealing the maximum potential of the solenoid valve in the system work, which is one of the important characteristics to characterize the working ability of the solenoid valve. In this paper, a numerical calculation method is used to build a finite element model of the solenoid valve electromagnetic field on the Ansoft Maxwell simulation platform. The model takes into account the nonlinear magnetization characteristics of soft magnetic materials and the air gap. The experimental results verify the accuracy of the simulation model, analyze the influence of the solenoid valve working air gap, pull-in area, coil aspect ratio and other parameters on the static characteristics of the solenoid valve based on the simulation model, and methods are proposed to improve the static characteristics of the solenoid valve.
