The application of three-dimensional hydroelastic analysis of ship structures in Pekeris hydro-acoustic waveguide environment

The application of three-dimensional hydroelastic analysis of ship structures in Pekeris... Abstract The hydroelastic analysis and sonoelastic analysis methods are incorporatedwith the Green’s function of the Pekeris ocean hydro-acoustic waveguide model to produce a three-dimensional sonoelastic analysis method for ships in the ocean hydro-acoustic environment. The seabed condition is represented by a penetrable boundary of prescribed density and sound speed. This method is employed in this paper to predict the vibration and acoustic radiation of a 1 500 t Small Water Area Twin Hull (SWATH) ship in shallow sea acoustic environment. The wet resonant frequencies and radiation sound source levels are predicted and compared with the measured results of the ship in trial. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Acta Mechanica Sinica" Springer Journals
