Abstract
In this paper, active vibration control of flexible structure by high-polymer piezoelectric films, which aims for the realization of smart structures, is investigated. At first, active vibration control method using piezoelectric films as sensor and actuator is discussed and the concept of distributed vibration control method is introduced. Then, several examples which are the author's studies are shown. The topics included are vibration control experiments of cantilever beams using rectangular-shaped sensor/actuator pairs, vibration control experiments of simply supported beams using a triangular sensor/actuator pair, wave absorbing control of cantilever beams using two pairs of triangular sensor/actuator, and vibration control experiments of cantilever beams and circular rings by a self-sensing actuator using piezoelectric films of different thickness. Finally, an overview of this study toward the future is presented.
