Paper Abstract

Due to possessing virtue of simple structure, small volume, fast response and good controllability, the actuator made with Terfenol-D exhibits widely potential application in the field of vibration control, precision machine and instrument, micro-driven and sonar system. One key technology for designing above devices is gain efficient and uniform bias magnetic field. In this paper, using software of ANSYS, the distribution character of magnetic field of magnetostrictive actuator was analyzed; methods to improve uniformity of magnetic field were also discussed.
