要約(日本語): The aim of this study is to present a new two degree of freedom (DOF) linear resonant actuator (LRA) and its motion control method. The design method of two DOF LRA that resonates with only detent force without mechanical spring is proposed. One of the characteristics of this actuator is that a centering force is generated according to the moving distance regardless of the moving direction on the X-Y plane. By using this feature, various resonance motions on the x-y plane can be realized. This paper also proves that reciprocating resonance motion, elliptical motion, scroll motion, and complex resonance motion can be controlled. The effectiveness of the proposed method is verified by finite element analysis (FEA) results and numerical simulation.
