The growth of fluid power has accelerated with desire to control ever-increasing quantities of power and mass with higher speeds and greater precision. More specifically, where precise motion control is desired and space and weight are limited, the convenience of a high power-to-weight ratio makes hydraulic servomechanisms ideal control elements. The objective of the monograph is to develop a design methodology to study the dynamics of the Fluid Structure Interaction (FSI) of jet pipe Electrohydraulic Servovalve with built-in mechanical feedback using Finite Element Method. The FSI is...
