仿生型步进式直线驱动器的研究

本文提出一种新型直线驱动器的仿生动作原理，并设计出两种机械结构及其控制器。实验表明，这类驱动器具有精度高，步距可变，输出力大，行程长，结构简单，体积小，内藏传感器，具有极好输出特性等特点。这类驱动器适用于一切超高精度的直接驱动。

STUDY ON BIONIC-TYPE STEPING LINEAR ACTUATOR

A new bionic action principle of linear actuator is presented.The two prototypes of linear actua-tor on this action principle and its controller are designed.Experiment results show that the actuator func-tions and performs with ultrahigh accuracy,changeable steplength,large drive force,long stroke and bestoutput,characteristic due to built-in sensor,although it is simple in structure,small in volume. These actua-tors are applied to all ultrahigh accuracy direct drive.
