船舶减摇鳍的使用工况包括航行状态和零航速状态，当船舶在航行过程中，减摇鳍与流体发生相互运动，在减摇鳍表面产生抗倾覆力矩，保证船舶的航行稳定性；当船舶处于零航速状态下，由于海浪、海风等干扰力矩的作用，同样会使船舶发生横摇、纵倾等运动，因此也必须进行减摇控制，此时船舶的减摇是利用机械结构使减摇鳍运动，产生抗倾覆力矩。本文针对船舶横摇和减摇鳍的流体动力学特性进行系统的建模，分别从主动式减摇鳍的翼型、形状、分布定位等内容进行展开，有助于提升现有船舶减摇鳍的设计水平。
The service conditions of Ship Fin Stabilizer include navigation state and zero speed state. When the ship is sailing, the fin stabilizer and fluid move each other and produce anti overturning torque on the surface of fin stabilizer to ensure the navigation stability of the ship. When the ship is in the state of zero speed, due to the action of interference torque such as sea wave and sea wind, the ship will also roll and pitch. Therefore, roll reduction control must also be carried out. At this time, the ship's roll reduction is to use the mechanical structure to move the fin stabilizer to produce anti overturning torque. In this paper, the hydrodynamic characteristics of ship rolling and fin stabilizer are systematically modeled, which is carried out from the airfoil, shape, distribution and positioning of active fin stabilizer, which is helpful to improve the design level of existing ship fin stabilizer.
