A three-dimensional sono-elastic method of ships in finite depth water with experimental validation
In order to conduct the comprehensive analysis of fluid-structure interactions, acoustic radiation and acoustic propagation, a three-dimensional sono-elastic method in the frequency domain is proposed in this paper. In this method, the three-dimensional hydroelasticity theory of floating structures is incorporated with the hydro-acoustic propagation theory by introducing frequency domain Green's functions appropriate to the ocean hydro-acoustic waveguide environment. The simple source boundary integral approach is adopted to obtain the sono-elastic response in the frequency domain. In order to deal with the irregular frequency problem in this approach, a Closed Virtual Impedance Surface (CVIS) method is put forward. At last, the sono-elastic method is validated by calculating the acoustic radiation of a floating elastic spherical shell and an experiment of the underwater acoustic radiation of two ring-stiffened cylindrical shell models.
