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

Abstract

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