The issue of modeling and simulation of a kind of high speed solenoid valve used for an electronic control system of a certain engine was discussed.According to the analysis of the operating principle of the high speed solenoid valve

the mathematical model of high accuracy for the high speed solenoid valve was built by use of the simulation software AMESim.The analysis on the duty ratio-volume flow characteristic was completed according to the simulation result of the model.By comparison of the experimental data of the electrical valve

the accuracy and precision of the mathematical model were analyzed.Simulation results show that the error of the duty ratio-volume flow characteristic of mathematical model for high speed solenoid valve is no more than 8%

thus satisfying the accuracy requirements set by the products.
