Abstract: The occurrence of parametric rolling will threaten the ship safety. The bilge keel is selected as the device of stabilization and suppression of the parametric rolling for an ONR tumblehome ship. The influence of the installation angle and breadth of the bilge keel on the roll damping is calculated based on the viscous CFD method. A new retractable bilge keel stabilizer is designed to improve the stabilization effect. The rolling characteristics of the ONR tumblehome ship in regular head seas with different bilge keel schemes are analyzed by using the three-dimensional potential flow method. The simulation results show that the bilge keel can effectively suppressthe parametric rolling and stabilize the ONR tumblehome ship.In particular, the designed retractable bilge keel can obviously suppressthe parametric rolling.

Key words: parametric rolling, ONR tumblehome ship, numerical simulation, bilge keel

摘要: 参数横摇的发生会危害舰船的航行安全性。该文以ONR内倾船作为研究对象,选用舭龙骨作为ONR内倾船参数横摇减摇及抑制设施,基于黏流CFD方法,计算了舭龙骨的安装角度和宽度对横摇阻尼的影响规律;为了提高减摇效果,设计了一种可收放式的新型舭龙骨减摇装置,利用三维势流分析方法,研究了该装置不同参数方案下的ONR内倾船规则迎浪下的横摇运动特性。仿真结果表明,舭龙骨减摇装置可以对ONR内倾船的参数横摇运动产生较好的抑制和减摇效果,特别是文中设计的收放式舭龙骨方案,对参数横摇的抑制效果非常明显。
