Abstract
Rotary actuation generated by a cyclic symmetric stator vibrations have been investigated in this research by using numerical finite elements. The cyclic symmetric stator’s vibration response is characterized through parameter studies with varying number of protrusion fingers, their geometry parameters and contact angle between stator fingers and rotor. The structure responses on the stator disk and protrusion finger of the stator have been experimentally validated in this study. The split-frequency structure vibration response on the protrusion fingers has been found to be catalogued by the number of the finger on the stator disk. The radial deformation of the protrusion finger was examined and characterized by two different parameters, namely the displacement strength and the bending deformation angle. The numerical studies in this research were validated by experimental mechatronic prototype, from which good agreement between the two and consistency between prediction and measurement were found.
