摘　　要：针对超磁致伸缩材料微位移驱动器在精密定位控制中存在的迟滞和位移非线性等不足,对超磁致伸缩材料微位移驱动器进行实验研究,介绍了微位移驱动器中预紧机构和放大机构的设计理论、设计过程和研究方法。研究结果表明:微位移驱动器的控制精度高、重复性好且适用范围较大。In light of the shortcomings of giant magnetostrictive materials used in the micro displacement actuators,such as hysteresis and nonlinear in precision positioning control,the experimental study on micro displacement actuators of giant magnetostrictive materials is carried out.This paper introduces the design process,design theory and research methods of pre-tightening mechanism and amplification mechanism in a micro displacement actuator.The experimental results show that the micro displacement actuator is of higher accuracy and better repeatability.
