Analysis and Optimization of Pressure-flow Characteristics of Pilot Solenoid Valve of Continuous Damping Control Shock Absorber
摘要
Abstract
The pilot solenoid valve regulates the internal oil flow of the shock absorber by controlling the main valve pressure,thereby affecting the damping force.A reasonable design of pressure-flow characteristics can broaden the range of damping adjustment to meet the needs of different working conditions.In this study,the pressure-flow characteristics of the pilot solenoid valve for an automobile continuous damping control shock absorber are optimized.Firstly,the hydrodynamic model and steady state force model of the oil flowing through each damping hole are established based on the fluid dynamics theory.The relationship between the electromagnetic force and the input current is determined with the electromagnetic magnetic circuit model of electromagnetic theory,and then the hydraulic simulation model is established.Subsequently,with the help of the solenoid valve performance test bench,experimental comparisons are carried out to verify the accuracy of the simulation model.Finally,the key structural parameters affecting the pressure-flow characteristics of the pilot solenoid valve were analysed to determine their importance using full factorial analysis of experimental design,and the key dimensions were optimised using a genetic algorithm,with the optimisation effect improved by 10.14％.关键词
