[0002] In the field of solenoid valve technology, high-speed switching solenoid valves, as an important control element, are widely used in vehicle braking systems, air conditioning, energy, aerospace and other fields due to their low price and excellent anti-pollution performance. At the same time, high-speed switching solenoid valves have the advantages of fast response, high-frequency switching, and precise control, which can meet the requirements of modern engineering for high performance and high efficiency. With the continuous development of science and technology, high-speed switching solenoid valves are expected to show broad prospects in more fields. Because of the advantages of low cost, short time cycle, and high flexibility of numerical simulation calculations, more and more researchers use numerical simulation methods to analyze the characteristics of valves, thereby optimizing and improving the performance of valves.

[0003] In the prior art, the specific steps of high-speed switch solenoid valve simulation are as follows: deeply understand the structure and working principle of the high-speed switch solenoid valve, and establish a mathematical model based on its electromagnetic characteristics, flow field characteristics and mechanical characteristics. Set simulation parameters according to actual needs and select appropriate simulation software. In the simulation software, convert the mathematical model into a simulation model and substitute the set parameters, run the simulation calculation, and obtain the simulation results of the electrical, magnetic and fluid mechanics characteristics of the solenoid valve.

[0004] The defects of the above-mentioned existing technologies are: the simulation is mainly focused on a single physical field, such as an electromagnetic field or a fluid mechanics field, and lacks comprehensive consideration of multiple physical fields, resulting in insufficient simulation of complex physical processes in the real working environment of high-speed switching solenoid valves, affecting the accuracy and reliability of the simulation.

Import the fluid simulation model of the high-speed switch solenoid valve into the meshing software Fluent for meshing. The specific process is as follows:

[0049] 2.1 Set the local size and global size, perform local encryption at the narrow valve orifice, divide the surface mesh, set the number of boundary layers, and use the "tetrahedron" mesh for volume mesh division;
