It is of great importance to evaluate the hull structural vibrations response of large ships in extreme seas.Studies of hydroelastic response of an ultra large ship have been conducted click here with comparative verification between experimental and numerical methods in order to estimate the wave loads response considering hull vibration and water impact.A segmented self-propelling model with steel backbone system was elaborately designed and the experiments were performed in a tank.Time domain numerical simulations of the ship were carried out by using three-dimensional nonlinear hydroelasticity theory.

The results from the computational analyses have been sequal eclipse 5 battery correlated with those from model tests.
