• Multimodal Vibration Control Using a Self-sensing Actuator with Laminated Piezoelectric Films

抄録

In the authors' previous report, a self-sensing actuator using laminated piezoelectric films with differnt thickness and area was proposed, and the validity of the proposed method against the lowest vibration mode was shown by performing vibration control experiments of a cantilever beam and a simply-supported plate. In these experiments, however, only rectangular shaped films were used, and furthermore, vibration control effects against higher modes was not verified experimentally. In this report, the present method is applied to multimodal vibration control of simply supported beam by using piezlelectric two films of differnet shapes and orientations. Two types of self-sensing actuators are proposed and five conbinations of thickness, shape, and oriantations of the two piezoelectric films are considered and vibration control effects are compared theoretically. Finally, vibration control experiments are performed using laminated triangular-shaped piezoelectric two films with different skew angle, and it is shown that vibration control effect was obtained against first and second modes of the beam.
