摘　　要：对气液增压系统的组成、原理及关键技术进行了阐述。为了改进气液增压式系统的动态性能,对电磁换向阀进行了数学建模,并采用建模分析软件MATLAB/Simulink进行仿真计算,分析了气隙长度、驱动电流大小、线圈匝数、气源压力等关键参数对电磁阀工作性能的影响。根据仿真分析的结果,对现有气液增压系统的关键部件提出了改进方案,实验结果证明了优化方案的可行性。This paper reviews the composed principle and key technologies of gas-liquid pressurization system. In order to improve the dynarnies performance of the gas-liquid pressurization system, the mathematical model of sole- noid valve is established. And furthermore , performance of solenoid valve affected by some key parameters such as the gas length, the drive current, the turn ratio, the air pressure value and so on are analyzed by means of the sim- ulation software MATLAB/Simulink. Improved experimental system on key parts of the gas-liquid pressurization system is carried out. The results show the feasibility of the optimization through the experimental test.
