Construction of prediction model for electromagnetic force onhigh-speed solenoid valve of electric-controlled booster pump

In order to scientifically predict the electromagnetic force performance of the electric-controlled booster pump high-speed solenoid valve for the ultra-high pressure common rail system, the response surface method was used to construct the electromagnetic force prediction model to achieve efficient prediction and optimization of its performance. A three-dimensional finite element simulation model of the high-speed solenoid valve for the electric-controlled booster pump was established and verified by experiments. Based on the idea of experimental design, key factors such as drive current, working air gap, armature thickness, number of coil turns, main magnetic pole radius, and orifice radius were selected. 54 sets of sample points of electromagnetic force numerical test research program were developed through the response surface method. The electromagnetic force prediction model was constructed. After R test, and the simulation test verifies that the electromagnetic force prediction model has a maximum error of 1.3%, indicating that the model can accurately predict the electromagnetic force of the electric-controlled booster pump high-speed solenoid valve and provide a theoretical basis for the design and optimization of the ultra-high pressure common rail system control system.
