Vibration Analysis of Coupled Fluid-Filled and Immersed Thin Composite Cylinders abstract
When a shell structure filled and immersed with a fluid, which introduces significant fluid loading effects, it warrants a coupled fluid-structure analysis. In this paper, a finite composite cylinder is modeled for coupled frequency analysis using finite element method. The fluid-structure coupling effect was considered in the analyses. The first eight coupled natural frequencies were obtained. Then, the effects of shell parameters,such as boundary conditions, thickness-to-radius, length-to-radius, modal number in the axial direction, m, and modal number in the circumferential direction, n on the coupled frequencies of the composite cylinder are investigated. The obtained results for a fluid-filled and a submerged isotropic thin-walled cylinder are compared with the available results from wave propagation method to verify the developed procedure.
