摘要

Delayed Resonators (DR) refer to a special type of active vibration absorber system. An intentionally delayed feedback control is used to bring an absorber sub-structure to resonance, in turn canceling vibrations in the primary structure. So far, this theory has been applied to traditional mechanical vibration absorbers with proof masses. This study proposes a new venue for DR-based vibration control using piezoelectric networks. The inherent electro-mechanical coupling of piezoelectric materials has enabled the use of electrical circuits to absorb vibrations in mechanical structures. The DR principles are applied here to create a resonating electrical circuit which offers ideal vibration absorption performance. Experimental studies are also presented to demonstrate the results.
