The Modeling and Simulation of Water Hydraulic Overflow Valve with Giant Magnetostrictive Actuator

This paper puts forward the structure of water hydraulic overflow valve with Giant Magnetostrictive Actuator. In the condition of ignoring magnetic leakage and magnetic force uneven, we deduced the static output displacement and force equation of the GMA. By establishing a mathematical model, we get the dynamic response of the time and output force in the rated electricity flowing down with the simulation. GMA has the simple structure, good linear, enough output force and displacement, and high response speed and other significant advantages.
