Abstract  This paper presents the theoret ical and experimental study of magnetost ict ive mini-actuator.Transfer funct ion and dynamic modeling are described and discused as well. The modeling can be widely used in the design of giant manetostrictive actuator. Experiments show the mini-actuator designed and
developed by ourselves can meet the requirements of species displace and vibration control system. T he experiment results and the computer simulation results show that the device has good properties in low frequency range.

Key words： Terfernol-D      mini-actuator      dynamic characteristics
