摘　　要：随着低航速甚至零航速舰船在海上作业的可能需求日益增大,如何减轻低航速舰船的横摇运动是个亟待解决的问题。本文利用计算流体力学软件,数值模拟减摇鳍简单运动,以达到显著减弱零航速船舶横摇运动的目的。首先,在有航速和零航速两种情况下,对减摇鳍作简谐运动时所受的流体动力进行数值模拟,计算结果与文献中的试验和数值结果比较吻合;接着,计算分析并获得减摇鳍运动与船舶横摇运动之间的关系;最后,通过对船模在相同波高、4个不同周期的规则波中进行减摇效率模拟,发现零航速减摇鳍的减摇效率至少为61%,最高可达81%。With the possible demand for the ship operation at low or zero speed increasing,how to reduce the ship roll motion is an important issue when the ship is at low speed.In order to significantly reduce the ship's roll motion,a computational fluid dynamics(CFD)software was employed to simulate the simple motion of fin stabilizers installed on a zero-speed ship.Firstly,the hydrodynamic forces acting on the fin stabilizer in sim⁃ple harmonic motion,with or without forward speed.were numerically simulated.The numerical results were in good agreement with experimental and numerical data found in literature.Secondly,the relationship be⁃tween the fin stabilizer motion and the ship roll motion was established.Finally,a zero-speed ship model roll motion was simulated in 4 regular waves,with the same wave height and different wave periods,and it is found that a roll reduction efficiency of between 61%and 81%is achieved.
