The low frequency dynamic responses of a submerged hull are presented. The solutions are in the form of a wave travelling in the axial direction. The submerged hull is modelled as a finite fluid-loaded cylindrical shell closed at each end by circular plates. The external pressure acting on the hull due to the fluid loading is analytically calculated using an infinite model. Axial and radial excitations set at the different places of the hull are considered to simulate excitation from the propulsion system and the excitation at one point in the middle of the shell. Four cases of excitations are discussed in details, corresponding to axial excitation at the centre of the endplate, axial excitation at the edge of the endplate, radial excitation at the edge of the endplate and radial excitation at the middle of the cylindrical shell. The contributions from the individual circumferential modes on the hull structural responses are studied. Results are presented by comparing the frequency dynamic responses of shell under axi-symmetric excitations with asymmetric excitations, two excitations in different directions but at the same point, two excitations at different points but in the same direction. The effects of endplates in different cases are also discussed. It was shown that the endplates mainly decrease the radial displacement at higher circumferential modes. Results from the analytical models are validated by numerical results from Ansys model, of which both the hull and the fluid are built by finite elements.
