Vibration analysis of a thin cylindrical shell

Abstract

In this paper, vibration characteristics of thin cylindrical shell are investigated by using & ANSYS WORKBENCH 14.0. Vibration response are investigated by Transient Structural analysis for the simply supported boundary conditions. It is also necessary to investigate the characteristics considering fluid-structure interaction (FSI) effect by System Coupling between Transient structural and Fluent flow. In this study, theoretical background and several finite element models are developed for cylindrical shells with fluid-filled annulus considering fluid-structure interaction. The effect of the inclusion of the fluid-filled annulus on the natural frequencies is investigated, which frequencies are used for typical dynamic analyses the equations of motion of the structure for the theoretical analysis are obtained from Love’s equation.
