Abstract

A fluid surface damping (FSD) element has been designed, produced and applied for the vibration suppression of a cantilever aluminum beam. The experimental steady-state frequency response of the treated beam, measured at the free end and subjected to a burst white noise excitation at the base, is determined and compared with the corresponding analytical results. The comparison shows a disagreement between the predicted and experimental results. Discussion of the potential sources of disagreement and of possible remedial measures is presented.
