ABSTRACT
The paper presents an experimental study to identify the dynamic parameters of a water-filled tank model. The experimental modal analysis approach involving the excitation at one point of the structure and acquisition of vibrations at selected points distributed over the tank surface allowed to determine the resonance frequencies, mode shapes and damping ratios. The main aim of the research was to examine the influence of the level of liquid on the modal parameters. The experimental study showed that the level of water in the tank had an important impact on the values of natural frequencies and damping ratios.
