This paper deals theoretically and experimentally with the nolinear vibrations of a structure caused by water sloshing in a cylindrical tank. The structure carrying the tank is horizontally subjected to a comparatively large sinusoidal excitation. In a theoretical analysis, the resonance curves are obtained by swept sine test in a numerical simulation of the modal equations. As a result, it is found that a swirl motion of the water surface and an almost periodic oscillation of the structure appear in certain regions of the excitation frequencies. In addition, a super-summed-and-differential harmonic oscillation can occur at the tuning frequency. These results agreed quantitatively with the experimental results.
