ON THE INFLUENCE OF THREE-DIMENSIONAL EFFECTS AND RESTRICTED WATER DEPTH ON SHIP HULL VIBRATION

In this note a finite element method for the calculation of the three-dimensional added mass of a vibrating ship hull is presented. The hull is approximated by a cylinder of the same overall dimensions as the ship and the mode of vibration is approximated by the vibration mode of a uniform free-free Bernoulli-Euler beam. The method has been compared with an analytical solution and with measured results. Finally, a parametric study of the effect of restricted water on the three-dimensional added mass is presented.
