The Effect of Hull Forms on the Rolling Motion

선형(船型)이 횡요운동(橫搖運動)에 미치는 영향(影響)

In this paper, the authors describe not only the linear-theoretical considerations of the hull forms which many schalors have been investigating by the hydrodynamics as to the rolling ships in the waves, but also measure the rolling angles of the models, the coefficients of the effective wave slopes, the forced rolling moments by the waves, the extinctive curves, and the amplitudes of the waves in view of changing both the drafts and the metacentres so that they may study the inclinations of models in the grinoll motion. Owing to the conclusions of these studies, we can learn the fact that the experimental results of the models in the waves agree almost to the linear-theoretical subjects.
