The new giant magnetostrictive material TbDyFe has the trait of output power large, displacement resolving power high and displaclement range great. If the material is used in the micro displacement actuator, the performance index of displacement actuator will be greatly advanced, which will impel the development of giant precision process technique. In the paper, the structure and the performance of giant magnetostrictive actuator are introduced, and the model of magnet machine coupling is analysed by the finite element method. It will redound to the computer simulation and the actuator analysis and its design.
