Comparison of damping performances of constrained viscoelastic layers and passive piezoelectric networks

Résumé

This work aims at comparing the damping performances of two passive treatments based on piezoelectric or viscoelastic patches. The motivation for such a comparison stems from the fact that the two damping treatments have been developed fairly independently, and are rarely compared. Firstly, the dynamic response of a simply supported metallic plate, equipped with constrained viscoelastic patches or piezoelectric patches connected to an electrical network, is measured experimentally. Secondly, a numerical model of the structure is set up and validated to evaluate the damping performances of both passive treatments under different configurations (for instance equal-mass and equal-thickness configurations). Finally, with regard to this work, the advantages and the limitations in using viscoelastic or piezoelectric treatments are discussed.
