Simulation Research on Coupling Relationship Between Energy Distribution and Dynamic Response of High-Speed Solenoid Valves

In order to study the energy distribution inside the high-speed solenoid valve and the coupling relationship between the energy parameters and the dynamic response, the performance of the high-speed solenoid valve was optimized. Firstly, the dynamic model of the high-speed solenoid valve was established based on the finite element method, and the accuracy of the model was validated through the experimental data. Secondly, based on the D-optimal design of experiments and the method of least squares, the response surface prediction model of the solenoid valve’s dynamic response characteristics was constructed, with the energy parameters as the factors. Finally, based on the meta-analysis method, the simulation analysis of the dynamic response of the high-speed solenoid valve with significant energy parameters and parameter interactions was carried out. The results show that the eddy energy E₁ is the relatively sensitive parameter affecting the response time of high-speed solenoid valve opening T_o among the single parameters, and T_o increases by about 25% with the increase in E₁. The interaction between E₁ and damping energy E₃ and between E₁ and Joule energy E₄ is the highly sensitive parameter affecting T_o, and the interaction between E₁ and E₄ is the highly sensitive parameter affecting the response time of closing T_c. The results also find that the factors that play a dominant role in the interaction parameters change with the range of values.
