Paper Abstract

By including piezo-materials into a light structure, it is possible to convert a part of its vibrational energy into electrical energy. When this electrical energy is addressed to a dissipative impedance, a damping effect is obtained. The achievable performances for various kinds of dissipative impedances are derived from modeling results. It is shown how the used dissipative impedance acts on the structure (mechanical equivalence) and how the obtained performances are related to a non-dimensional coupling factor. Finally numerical and experimental results from a case study are presented.
