An analysis of the dynamic response of a nozzle-flapper valve with integral squeeze film damper (SFD) is presented. An expression for oil film forces, including the effect of fluid inertia, has been derived using a first-order perturbation method. The nonlinear effect of flow control orifices is included in the simulation model. The effects of the squeeze film damper geometric coefficients have been examined and the flapper response to a step current input is modeled. The analysis also focuses on the relationships between output control pressure, input current, and supply pressure.
