Abstract

An approach for vibration delocalization of nearly periodic structures using piezoelectric networks with active coupling enhancement is presented. Piezoelectric networks are synthesized to reduce the localization effect by absorbing the vibratory mechanical energy into the electric circuits and distributing it through an additional strong electrical wave channel. The effectiveness of electro-mechanical coupling of the system is increased through the use of active actions via a negative capacitance circuit. It is demonstrated that the delocalization effect of the piezoelectric networks can be greatly enhanced by using the proposed treatment.
