Three-dimensional hydroelasciticity analysis of acoustic responses of ship structures
The three-dimensional hydroelasticity theory of ships1-3 was extended to include the effect of fluid compressibility. This enables the acoustic responses of a ship structure induced by the machinery or wave excitations being predicted with the inclusion of the free surface and the forward speed effect. A method for eliminating the irregular frequencies in the numerical analysis is proposed. The acoustic radiation of an elastic spherical shell was predicted and compared with analytical solution for validation. Illustrated in this paper are also the acoustic radiations of a submerged ring-stiffened cylindrical hull in the near field and far field.
