摘要：The driving principle and the structures of the giant magnetostrictive actuator are analyzed. On the basis of this work, the magnetic field in the actuator is mainly investigated from the aspect of the theoretical analysis and the experimental research, and a conclusion is drawn that the relation between the driving current in the giant magnetostrictive actuator and the driving magnetic field of the giant magnetostrictive stick is non-linear and of hysteresis. Moreover, the reason is analyzed and the foundation of further improving the performance of the giant magnetostrictive actuator is established.
