چکیده انگلیسی

The vibro-acoustic characteristics of a submerged shaft-hull system are investigated by numerical and experimental methods. A numerical model for the structure-fluid interaction of the system is formulated by the coupled finite element/boundary element methods. With this model, the influence of the shaft vibration on the dynamic and acoustic responses of the submerged shaft-hull system is analyzed via the modal decomposition technology. It is found that reduction of the stiffness of the stern bearing and symmetrization of the foundation can reduce the sound radiation from the submerged shaft-hull system subjected to transversal and axial force excitations, respectively. The numerical solutions are validated by the experimental results, and reasonable agreement is observed.
