The preliminary analysis was made on the hull vertical vibration of tankers in which the ship hull is simulated by the model of two parallel beams elastically connected. Each beam represents the side shell and the longitudinal bulkhead respectively, and the connecting springs the transverse structural members. The result shows that the relative deformation between these two beams is remarkable in the modes higher than 5-or 6-noded mode which means the elastic deformation of the cross section of the ship is significant, contrary to the assumption in the beam-theory calculation. As the mode becomes higher than these modes, there appear new modes in which the deflection of one beam is out of phase by 180 deg to that of another beam. (Author)
