N2 - The giant magnetostrictive actuator has some unique characteristic, such as high displacement resolution, big output torque etc, so is suitable for the field of ultra precise measurement and fine machining. The principle of the giant magnetostrictive actuator is based on magnetostriction, and Tb 0.27.Dy0.73Fe1.9 is drove by magnetic field. So the high resolution of the giant magnetostrictive actuator is relate to uniformity of magnetic field. Furthermore, the resolution of actuator is effect by output setup. Because of magnetic field asymmetry, the giant magnetostrictive actuator based on the principle of electromagnetism transforming can be easily causes of displacement nonlinearity. For this problem, the structure and principle of magnetic field is analyzed based on FEA. For improving the resolution farther, the flexible hinge is used to replace to the traditional output setup. At last, the principle of this type of actuator is validated through experiments.
