摘要：Within the frame of potential theory and the assumption of weak nonlinearity of wave motion, a numerical method is developed for the third order triple-frequency wave loads on fixed axisymmetric bodies in monochromatic incident waves. Applying the numerical code, numerical computations were carried out for surge and heave forces and pitch moments on a uniform cylinder, truncated cylinders and a hemisphere. Examinations were made on the contribution to third order forces and moments from potentials at each wave orders, and the relation of third order forces and moments with wave number and drafts of cylinders.
