加装舭龙骨对千吨级深V船型静水阻力和横摇运动的影响
Effects of bilge keel on a one-thousand-ton deep-vee monohull with calm water resistance and rolling motion
摘要
Abstract
Deep-vee monohull can offset the wave strength at the bottom of the hull, increasing the pitch damping and improving the pitch, surge, and vertical acceleration, reducing the slamming and deck wet-ness, all of which lead to better longitudinal sea-keeping performance. However, the roll at slow speed does not show any significant improvement. Aiming at the problem, fixing a bilge keel onto the middle part of the deep-vee monohull could improve the seakeeping performance, especially the roll of the ship in waves. In this paper, a one-thousand-ton deep-vee monohull's hydrodynamic performances with different bilge keel projects are numerically simulated, which guides the design of bilge keel projects for model tests. Then, three actual projects are designed for model test, whose results of seakeeping model tests reveal that the best project has a resistance performance increment less than 5%, and the seakeeping performance, espe-cially the roll of the ship, has a 30%improvement.关键词
