Dynamic Characteristics Analysis of Two-DOF Oscillatory Actuator and Experimental Verification of Prototype

摘要

Recently, linear oscillatory actuators have been used in a wide range of applications. In particular, small linear oscillatory actuators are expected to be used in haptic devices by being extended to provide multi-degree-of-freedom motion with arbitrary acceleration. In this paper, we propose a compact two-DOF oscillatory actuator that can move in various directions on a plane. The static and dynamic characteristics of the actuator are determined by the 3D finite element method. The effectiveness of this method is shown through a comparison of the measured results with the experimental results from a prototype.
