Abstract
A smooth impact drive mechanism (SIDM) is a linear actuator which utilizes the friction force between a friction bar and a moving object. In the previous researches, SIDM actuators were composed of a soft type multilayered piezoelectric element which can generate a large piezo electric displacement. However, it has a complex structure and the piezoelectric material has low Q value. Therefore, we proposed to utilize a resonant phenomenon for SIDM principle. In this case, the driving part is a hard type piezo element while enables to drive an actuator with large speed efficiently. In this study, we propose to make it possible to adjust resonant frequencies of a vibration element, and to design a resonant type SIDM actuator with a hard type single-layer piezoelectric element.
