Abstract

The use of passive viscoelastic damping and active piezoelectric damping in a hybrid side-by-side configuration is explored in this paper. The goal is to combine the strengths of both individual methods to achieve better damping performance when targeting a single eigenmode or multiple resonances. It is found that a hybrid configuration where a passive constrained layer element covers the strain peak of a mode, with a active element placed next to it performs better than a passive or active damping treatment of the same size. It is more robust and uses lower control gains than active vibration control, and changes the system dynamics less than passive methods.
