A Natural Sloshing Absorber for Vibration Control

Sloshing liquid in a container may be used to suppress excessive structural vibrations. The principle of control of sloshing absorbers, is very similar to that of the conventional tuned vibration absorbers. The fluctuating pressure forces of sloshing liquid is employed to provide the control effect, instead of the intentionally resonated auxiliary oscillator of a tuned absorber. This paper presents the results of an experimental study to investigate the effectiveness of the sloshing of the raw contents of a hen’s egg. The objective is to explore the possibilities of borrowing design characteristics to enhance the effectiveness of sloshing absorbers for structural control. To this end, experimental observations are presented in the form of design charts.
