Paper Abstract

A fluid surface damping (FSD) technique proposed for vibration suppression of beam-like structures is applied to a generic simply supported aluminum beam. The steady-state frequency response of the FSD-treated beam at the vicinity of one end, due to an applied white noise displacement excitation at the other end, is determined using the finite element method. The response is found over a range of frequency covering the first four resonant frequencies and over a wide temperature range. Comparison of the results with the corresponding ones of a beam treated with the constrained layer damping method indicates that the FSD technique has a much greater potential for the vibration suppression of beam-like structures. Results also indicate that the FSD technique can provide a good vibration suppression over a wider temperature range.
