Establishment of designing rules for giant magnetostrictive actuators

This article presents some basic rules of the design of giant magnetostrictive actuators on the basis of analyses of working characteristics of giant magnetostrictive materials and basic structure and working mechanism of actuators using these smart materials. A giant magnetostrictive actuator is designed for the active vibration control under instruction of these rules,and its trait is tested.According to experiment results the actuator worked as the design objective required,verifying the validity and practicability of these rules.
