Abstract
The issue of vibrations of fluid-filled compound shells is considered. The shell is supposed to be consisted of cylindrical and conical parts. The liquid is ideal and incompressible, and its motion is potential. The fluid pressure acting on the wetted shell surface is obtained from the linearized Bernoulli’s equation for a potential flow. The frequencies and vibration modes are defined using reduced boundary element method. Both sloshing effect and elasticity of the shell walls are taking into account. The possibility is discussed of replacing the compound cylindrically-conical shell by cylindrical one of the equal height at sloshing frequency analysis. The validity of hypothesis of spectrum separation for sloshing and elastic modes is testified. The most dangerous frequencies from the point of view of resonance and stability losing are estimated for compound cylindrically-conical shells.

Keywords
Compound cylindrically- conical shells, reduced boundary element method, sloshing, frequencies and modes of vibration
