Abstract

Highlights: Analyze the distribution characteristics and changing law of eddy current energy loss. Reveal the main reason for limiting the dynamic response time of HSV. There is a maximum value of rate of effective energy utilization of solenoid valve. Abstract: In the present investigation, a simulation of the dynamic characteristics of a high-speed solenoid valve (HSV) was performed using the finite-element method (FEM). The interrelation between power losses and the dynamic response of the HSV was investigated based on the FEM simulation model. The relationship between the boost voltage, dynamic response, and power losses was established according to the energy conversion at the HSV system. The simulation results indicated that as the boost voltage increases, the rising rate of the driving current at the solenoid valve increases sharply, which favors the quick opening of the solenoid, while the power losses caused by the eddy current at the iron core increase rapidly. The rapid increase in the energy loss of the eddy current was the main factor that limited the effectiveness of reducing the opening response time of the solenoid valve by increasing the boost voltage. Regarding the energy utilization, an optimal boost voltage existed, where the solenoid valve reached the highest energy utilization efficiency.
