【Abstract】 As a kind of high scientific and functional material, giant magnetostrictive material has been widely used in motor, aeronautic, robot manufacturing industry, as well as in intelligent structure, at present, there existed only feasibility research and experiment stage in material application and device improvement. based on static and dynamic characteristic experiment controlled by computer, found and grasped the basic characteristic of material, provided data for the research and application. In the static characteristic experiment, it is observed that the curve of force & displacement is the ring of hysteric. By the compute method, it is obtained that the experiment formula of the magnetostrictive valueALmax and the pre - stress and the best pre - stress value as well as the rule of the more pre - stress the more magnetostrictive force.更多还原
