The research develops a method to accurately model high speed on/off valves. Current valves designs both produced commercially and in research were investigated to study design tradeoffs. Modeling methods were also researched to understand the tradeoffs between accuracy, computational cost, and complexity. A design criterion was determined and from this, a prototype was developed. Modern numerical analysis tools were used to optimize the valve for on/off applications. Once the valve geometry was determined, a lumped parameter model was created of the valve. The analytical model focused on accurately modeling and connecting the fluid, electrical, and mechanical domains that resulted in a fast accurate model. This model was organized into a graphical blockset to assist in implementation.

After completing the analytical model, a prototype was manufactured to verify the model and validate the design of the valve. A laser test apparatus was used to measure valve stroke, and it was determined the valve had a minimum transition time less than one millisecond. Further testing was done to verify static and dynamic performance of the valve. Finally, applications of the valve were studied including a detailed analysis and testing of a Virtual Variable Displacement Pump (VVDP) system.
