Abstract：Terfenol-D magnetostrictive stick was placed on the tester that was initialized through compressing, electrifying and demarcating. Then tester coil was charged with the variational electricity. Different electric currents can cause regularly changes around the magnetostriction stick. Finally the strain displacement data transmitted were surveyed, and computations, summaries, and graph analyses were conducted based on these data. The rate of increment of Terfenol-D magnetostrictive stick magnetostriction coefficient was small during the origin period of magnetic field strength increasing. When actuating magnetic field strength continued to increase, the magnetostriction coefficient increased very quickly, and the linearity was good. When the magnetic field strength increased continuously, the magnetostriction coefficient became increasing slowly, and gradually tended to saturated condition. Magnetostrictive performance of Terfenol-D magnetostrictive stick surpasses other materials, and may carry on to the displacement controls precisely.
