Coupled Horizontal and Torsional Vibrations of Container Ships

Necessity of performing hydroelasticity analysis of large container ships is pointed out. For this purpose theory of coupled horizontal and torsional vibration is described. Beam finite element for vibration analysis, with eight degrees of freedom, which includes bending, shear, torsional and warping stiffness, is developed. Coupling between horizontal and torsional vibration is realised through inertia forces. Application of the theory is illustrated in case of a large container ship.
