| Abstract: | For increasing the driving efficiency of Giant Magnetostrictive Actuator(GMA), the key point is establishing the optimum magnetic circuit. Based on the Giant Magnetostrictive Material(GMM) axial pressure-magnetization equation, the relation between axial strain S33 and axial magnetic flux density B3 was Gained; according to the theorem of magnetic path, the effect of the magnetic structure and the relative permeability on the magnetic field was explored; using the finite-element method analyzed the magnetic field of the open and closed magnetic circuit, the method of the magnetic circuit optimum design was gained. |
