Research of Static and Dynamic Characteristic Simulation and Experiment for the Sliding Valve

in the hydraulic and pneumatic system, spool valve is the spool component which is widely used in various types of control valves. Generally, valve spool, use fluid pressures as control signals, regulates the opening and closing of the pipeline, the pressure and flow of the system automatically. The spool valves static and dynamic quality impacts the system performance greatly. Researching its characteristic has practical implications to improve the performance of related products and optimize the system design. This article aims at researching the influences, on the static and dynamic characteristics of the sliding spool valve, caused by different structural parameters, through mathematical modeling, computer simulation and experimental tests.
