Abstract

An experimental investigation of vibration delocalization of mistuned bladed disks using piezoelectric circuitry design is presented in this paper. A piezoelectric network is synthesized on a mistuned bladed disk, where its effectiveness is evaluated by comparing the blade tip displacements of the bladed disk with and without the circuitries. The possibility of improving delocalization by increasing the electro-mechanical coupling ability of the piezoelectric network using negative capacitance circuits is also investigated. The experimental results show that piezoelectric networking can reduce the localization level and adding negative capacitance can effectively enhance the performance, as predicted in previous theoretical studies.
