Abstract

The coupled structural-acoustic analysis of finite fluid-filled cylindrical shells is presented using the wave propagation method. For uncoupled analysis the natural frequencies of the shell by the present method are compared with the results available in the literature. For coupled analysis the comparisons of the frequencies by the present method and numerical finite element method boundary element method (FEM/BEM) are carried out. Through the comparisons it is possible to conclude that the present method is correct. It is a simple, non-iterative and relatively less computationally intensive method. It is shown that the fluid effect on the shell is significant. Ignorance of the fluid effect will lead to large errors in the vibration analysis of fluid-filled shells.
