稀土超磁致伸缩材料微位移机构综合实验研究

The General Experimental Investigation of Giant Magnetostrictive Mini Actuator

研究了稀土超磁致伸缩材料 (Tb0 .2 7Dy0 .73)Fe1 .9(商品名为Terfenol D)微位移机构的设计方法 ;建立了基于Terfenol D棒的高速强力微位移机构的动态响应特性模型 ;对该模型进行了计算机仿真 ,并与实验结果进行了比较、分析 ;给出了该机构的力特性、热特性。这些对基于Terfenol

This paper presents the theoretical and experimental study of magnetostictive mini actuator.Transfer function 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.The experiment results and the computer simulation results show that the device has good properties in low frequency range.
