Abstract: Haptic devices using asymmetric drive have been attracting attention. We have been studying 2-DOF haptic devices using a 2-DOF oscillatory actuator that can independently output asymmetric acceleration waveforms in 2 axes. This paper presents a new 2-Degree-of-freedom (DOF) linear oscillatory actuator. First, its static characteristics are computed by 3-D finite element method (FEM). Then, the dynamic characteristics of the actuator under asymmetric acceleration drive are clarified through FEM analysis and finally compared with measurements on a prototype.

Keywords: Electromagnetic analysis, finite element method, oscillatory actuator, haptic device, multi-DOF actuator
