BEAM MODELS FOR SHIP HULL VIBRATION ANALYSIS

Beam models used for hull vibration analysis are reviewed. The main conclusion drawn is that the Timoshenko beam theory, with a proper definition of the shear coefficient, can accurately predict the lowest vertical hull vibration modes and corresponding natural frequencies. For coupled horizontal-torsional vibrations a realistic modelling of major discontinuities in the hull beam is necessary in order to achieve reliable results.
