摘要
超磁致伸缩材料 （GMM） 是一种新型的功能性材料, 具有应变大、 可控精度高等优点, 是研制精密驱动器的理想材料.本文阐述了在交变磁场中超磁致伸缩棒产生震动, 通过对超磁致伸缩执行器 （GMA） 进行控制, 使其输出的震动位移在我们要求的位移误差范围内, 建立了超磁致伸缩位移控制模型并搭建了实验平台, 最终实现了GMA的振动位移误差在1μm的误差范围内, GMA的输出达到了理想精度要求.
Giant magnetostrictive material （GMM） is a new type of functional material with the advantages of large strain and high controllability. It is an ideal material for the development of precision actuators.This paper described the generation of vibrations in an alternating magnetic field by controlling the Giant Magnetostrictive Actuator （GMA） so that the output vibrational displacement was within the range of the displacement error we require. The displacement control model was extended and the experimental platform was set up. Finally, the vibration displacement error of GMA was within the error range of 1μm, and the output of GMA reaches the ideal accuracy requirement.
