针对深 V 船型在静水中零速工况下减横摇的需求，分别以某母型船的光体、加装舭龙骨和采用双折角线三种设计方案开展了船体静水自由横摇运动的数值模拟和横摇阻尼的数值预报研究。由于船舶的横摇运动受流体粘性的影响十分显著，准确预报船体的横摇阻尼必须计及粘性阻尼成分的因素。论文提出了一种将能量法和 RANSE 方程相结合的数值模拟方法，对比分析了三种船型方案的船体自由横摇特性，阐述了减横摇设计对线性和非线性横摇阻尼的影响规律。
針對深 V 船型在靜水中零速工況下減橫搖的需求，分彆以某母型船的光體、加裝舭龍骨和採用雙摺角線三種設計方案開展瞭船體靜水自由橫搖運動的數值模擬和橫搖阻尼的數值預報研究。由于船舶的橫搖運動受流體粘性的影響十分顯著，準確預報船體的橫搖阻尼必鬚計及粘性阻尼成分的因素。論文提齣瞭一種將能量法和 RANSE 方程相結閤的數值模擬方法，對比分析瞭三種船型方案的船體自由橫搖特性，闡述瞭減橫搖設計對線性和非線性橫搖阻尼的影響規律。

Based on the ship motion of free roll decay in calm water ,the purpose of present paper is to provide a method to estimate the roll damping ratio for three kinds of deep‐V hulls including the bare hull ,hull with bilge keel and hull with double chine lines .As the viscous effect is a notable factor in the roll motion ,the proposed method should take the viscous damping components into account ,which is combined with the energy method and RANSE simulation .The comparison anal‐ysis of free roll motion characteristics is carried out for three kinds of hull forms and the relationship of anti‐roll design to the linear and nonlinear roll damping components is conducted .
