Abstract

A remote energy-absorbing technique for the vibration suppression of beams is introduced. The technique is based on the idea of coupling the primary beam to a remote dynamic absorber (RDA) beam electromechanically via piezoelectric elements. A thorough experimental/analytical investigation of the concept, using a RDA beam identical to the primary beam as had been suggested previously, has been conducted. In addition to elucidating the limitations of the concept, the investigation demonstrated that using identical RDA would not work. Instead, a tuned RDA, where the electromechanical coupling stiffness is incorporated in the RDA, is proposed and analytically studied. The study suggests that this tuned RDA concept is valid and may even be practical.
