Abstract
In this paper we consider vibrations of cylindrical and conical baffled fuel tanks partially filled with a liquid. The liquid is supposed to be an ideal and incompressible one and its flow introduced by the vibrations of a shell is irrotational. The problem of the fluid-structure interaction was solved using the single-domain and multi-domain reduced boundary element methods. The rigid baffled tanks with different annular orifices were considered. The dependencies of frequencies via the orifice radius at different values of filling level were obtained numerically for vibrations of the fluid-filled tanks with and without baffles.
