| Popis: | Identifying a vessel global eigen vibration modes during the early stages of the design process is necessary, as it allows the prediction of special phenomena such as springing, whipping or other different resonance condition, that can lead to an uncomfortable working environment or, in extreme cases, even damage to the structure or equipment. An advanced approach for assessing the ships’ eigen vibration characteristics is based on the 3D-FEM method. This research is focused on analysing the eigen global vibration frequencies, for vertical, horizontal, and torsion modes, of a 9000 tdw tanker, pointing out the influence of the surrounding water by hydrodynamic added masses formulation. |
