Abstract

Here, based on main excitation of ship’s main engine, anti-resonance frequencies of hull girder were calculated, and a hull vibration design method based on anti-resonance frequencies allocation was proposed. With this method, the excitation frequency could be set as the anti-resonance frequency. By modifying structural stiffness or mass, vibration responses of important positions of a hull, such as, superstructure or mast etc. were zero under the anti- resonance frequency, and the vibration response of the hull under this frequency could be obviously reduced. The effectiveness of the proposed method was verified with numerical examples.
