【Abstract】 A unmerical method based on the STF method is developed to calculate the motion and wave-force responses of a near free-surface body in the regular and irregular waves.The mean drift wave forces are obtained in terms of the Newman slender-body theory with the three-dimensional modifications.The motions and wave-forces of a typical submerged body in the frequency domain and their transient responses in the time domain are given in several submerged depths and wave directions.The good agreement of the numerical results with the experimental results shows that the numerical method of this paper is valid and can be used to predict the seakeeping performance of the submerged body in the waves.更多还原
