A Comparison of the Hydrodynamic Characteristics of U, V Thpe Ship in Pitching and Heaving

U, V선형(船型)의 종요(縱搖) 및 상하요시(上下搖時)의 유체역학적(流體力學的) 특성비교(特性比較)

This paper compared the seakeeping quality of U, V type ships in infinite depth by using the finite element method. From the calculated results, it is found that heaving and pitching motions of V type are comparatively better than those of U type ship in the water of infinite depth and the reversed phenomenon occures in the water of finite depth. And the seakeeping quality of U type is better than V type ship in larger ranges than the nondimensional wave number 2.0.
