Abstract

In this paper, a numerical simulation is presented that shows active and passive vibration confinement of a pinned- pinned beam. The beam is divided into three regions: an isolated, a transition, and a localized region. Two dynamic vibration absorbers are used in conjunction with two pairs of piezoelectric transducers with a feedback law to reduce the displacement amplitudes in the isolated region and to confine the vibrations to the localized region. The development of an eigenvector shaping technique is also shown. This technique shapes the eigenvectors of the uncontrolled beam to confine vibrations to the localized region. Finally, the numerical results of a randomly forced and a harmonically forced controlled pinned-pinned beam are presented. These results show that the combination of active and passive vibration confinement reduces the total power required for active vibration confinement and demonstrate that piezoelectric transducers are viable actuators for vibration confinement applications.
