Modal Analysis and Control of Bowl Parts Feeder Activated by Piezoactuators

초록

This paper presents a new vibration mechanism activated by piezoactuators. A finite element model of the piezoactuator-driven bowl parts feeder is eatsblished and modal parameters are calculated. The vibrating mechanism is analyzed by investigating moving velocity of the parts with respect to the intensity of the voltage. This result may provide very usful information to develop practical parts feeder controlled by piezoactuators.
