Accordingly, the design method for this resonant actuator that resonates using its detent force without mechanical spring is proposed. In this actuator, a centering force is generated according to the moving distance, regardless of the moving direction on the X-Y plane. Using this feature, various resonance motions on the X-Y plane can be realized. This study also proves that the reciprocating motion, elliptical motion, and scroll motion can be controlled. The results of finite element analysis support the characteristics of the proposed actuator, which were compared to the results of measurements on a prototype. Finally, the effectiveness of motion control was validated through the prototype.本誌: IEEJ Journal of Industry Applications Vol.10 No.4 （2021）本誌掲載ページ: 436-442 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/10/4/10_20006072/_article/-char/ja/ Show more
