Sažetak
Non-linearity arising from the ship motion at large amplitude waves can’ t be neglected, especially in wave load, as in case of linear model. The wave load numerical model in large amplitude waves is presented. Main source of non-linearity, focused on in this work, involves time dependent hydrodynamic coefficients and excitation due to changing of cross section drought because of ship motion and wave passing. The load problem has been solved on harmonic waves in the frequency domain within vertical longitudinal plane. Vertical shear force and vertical bending moment in head waves are analyzed. As the source for linear and non-linear equation formulation, for motion, as well as for the wave load, modified Salvensen-Tuck-Faltinsen strip theory was used. The results are presented for S175 container ship and show non-linear effects in motion and hull load. They are in the form of high order wave load harmonic transfer functions and longitudinal distribution of the wave load along the ship hull.
