In this paper through the characteristic experiment of the giant magnetostrictive actuator, the relation between the magnetostrictive strain and the electric current under the different pre-stress is achieved. And the experiment formula between the maximal magnetostrictive strain and the pre-stress under the maximal electric current is founded. The optimal working pre-stress is established through the analysis to the data of the experiment. Then the characteristic of the magnetostrictive actuator under the optimal working pre-stress is discussed, and the experiment formula between the magnetostrictive strain and the electric current is founded. And, the 3-D interpolation curve of the magnetostrictive coefficient, pre-stress, and the electric current is achieved through the multidimensional interpolation. Last, magnetostrictive coupling coefficient is measured. Through the analysis of the experiment, some characteristics about the magnetostrictive strain, pre-stress, and the electric current have been established.
