Abstract

This chapter describes both steady-state and quasi-periodic response regimes in equivalent mechanical model of partially filled liquid storage tank which is subjected to external ground excitation. Nonlinear and moderate amplitude sloshing is considered. The sloshing mass is essentially smaller than the overall mass of the tank, so the reduced-order model (ROM) is actually equivalent to the thoroughly studied cubic nonlinear energy sink (NES). The dynamical responses captured by the ROM are qualitatively in good agreement with previous experimental, computational, and theoretical results.
