基于SimulationX的新型先导比例方向阀仿真研究

Involving electric, magnetic, mechanical, hydraulic and other disciplines, proportional directional valve is one of the important components of hydraulic system, mainly used to control the moving direction and speed of the hydraulic actuators. This paper introduces the displacement - pilot flow feedback principle only for two-position two-way cartridge valves and the structure of new three-position four-way slide valve application of the principle. In addition, this paper uses simulation software SimulationX to establish model of the proportional direction valve . Through simulation analysis, the dynamic-state and steady-state simulation curves of the proportional directional valve are obtained, which confirms the feasibility of the control principle.
