摘要:

针对超磁致伸缩驱动器存在行程短的问题,将音圈电机与超磁致伸缩驱动器结合,研究一种大行程宏微驱动器的新结构,并采用ANSYS Maxwell进行仿真,得出在不同宏动位移情况下磁力线分布;计算了宏动力和波动力范围,得出宏动定位的最佳范围;推导出微动线圈内GMM棒轴线的平均磁场强度随宏动位移和宏动线圈厚度的变化规律。验证了大行程宏微驱动器的可行性。

Abstract:

Aiming at the problem of short stroke of giant magnetostrictive actuator, a new structure of large-stroke macro-micro driver was studied by combining the voice coil motor with the giant magnetostrictive actuator, and the distribution of magnetic force was obtained by ANSYS Maxwell. The macro-dynamic range was calculated and the optimal range of macro-dynamic positioning was obtained. It is concluded that the average magnetic field intensity of the micro-actuator in the micro-motion coil varies with the macro-dynamic displacement and the thickness of the macro-moving coil. The feasibility of the large-stroke macro and micro driver is verified.

Key words: large-stroke, macro and micro drive, giant magnetostrictive actuator, thrust ripple, magnetic field intensity
