Experimental Determination of Waveexcited Forces and Moments Acting on a Ship Model Running in Oblique Regular Waves

摘要

The wave-excited forces and moments acting on a restrained Series 60 (C sub b = 0.60) ship model advancing at constant speed in regular oblique waves were experimentally determined. The oscillatory components and steady mean components of sway force, yaw moment, heave force, and pitch moment are presented in nondimensional coefficients, and their phases are given. The forces and moments vary little with forward speed of the model. The mean component of the forces or moments, in some cases, amounts to a fairly large portion of the oscillatory forces or moments. The experimental results are compared with available theoretical results. (Author)
