摘　　要：减摇鳍是一种特种减摇装置,它在船舶减摇装置中占有重要地位,本文首先对低航速减摇鳍在水中运动所受的作用力进行分析。其次,利用计算流体力学仿真软件Fluent对减摇鳍在低航速状况下进行仿真分析,并利用Matlab拟合出低航速减摇鳍的动态升力模型。最后,对拟合出的动态升力公式进行验证。结果分析表明:拟合出的动态升力公式可以很好的反应减摇鳍在低航速海况下进行主动拍击过程所产生的升力,可以为舰船在低航速海况下设计减摇控制系统提供一定的参考。Anti-rolling fin is a kind of special stabilizer,it occupies an important position in ship stabilizer device,in this paper,first of all,analysis the dynamic force of low-speed anti-rolling fin in the water. Second,anti-rolling fin simulation analysis is carried out under the condition of low speed by using computational fluid dynamics simulation software Fluent,and use the Matlab fitting out of the low speed dynamic lift formula of anti-rolling fin. Results show that the fitting of anti-rolling fin dynamic lift formula can very kindly response active flapping process in low speed sea condition,provide certain reference for the stabilization control system of ship at low speed sea condition.
