OMA experimental identification of the damping properties of a sloshing system

In the paper, an experimental method based on the Operational Modal Analysis (OMA) approach will be developed for the estimate of the damping properties of a sloshing system. The considered system will mimic a wing-like structure carrying fluid simulating the sloshing typically occurring in a flying wing. The experimental investigation will take advantage of the environmental testing facility available at the Department of Mechanical and Aerospace Engineering of the University of Rome "La Sapienza". The sensitivity of the damping estimates to the type, direction, and level of excitation as well as to the different filling levels will be studied and compared with similar results already achieved by the Department of Aerospace Engineering of the University of Bristol. The presented results, will serve the SLOshing Wing Dynamics (SLOWD) European funded project for the accuracy assessment.
