Simulation Study on Solenoid Valve of Hydraulic Control Unit

Abstract

In the research and development and improvement of the wet double-clutch automatic transmission, the hydraulic control unit has always been the focus of attention in the industry, and the working characteristics of the solenoid valve will directly affect the control effect of the hydraulic control unit, which in turn affects the quality of the vehicle’s shifting action. [1]This article is based on a hydraulic control unit, using its rich component library on the AMESim software platform, according to the working principle of the solenoid valve, the simulation model of various types of solenoid valves in the hydraulic control unit is established, and the exploration design module is used to the various parameters in the valve that are not easy to obtain directly are identified based on genetic algorithm, and the parameters in the model are optimized; then the S function is generated through the interface in AMESim, and each solenoid valve is simulated with the help of the numerical calculation ability of Matlab to obtain The simulation results of the solenoid valve working process are presented.[2, 3].
