Analysis of Static and Dynamic Characteristics of Sliding Spool Valve by Simulations and Experiments

摘要

In the control system of hydraulic and pneumatic, sliding spool valve is the spool component which is commonly used in various types of control valves. Valve spool general with fluid pressure as the control signal to automatically adjust opening and closing the pipeline, the system pressure and flow. The static and dynamic quality is a greater impact on the performance of the system, it's with practical significance to study its properties to improve related products' performance and optimize the system design. In this paper, mathematical modeling, computer simulation and experimental tests are used to study different structural parameters impact on the static and dynamic characteristics of the sliding spool valve.
