Abstract Fin stabilizers have been widely used to reduce the roll motion of ships at medium-high velocities. However, the anti-rolling efficiency of the traditional fin declines rapidly as the speed of the ship decreases. To enable more efficient use of fin stabilizers across the whole speed range, dynamics of fins at zero-low velocity were derived. Then, the proposed model was verified by experiment and the numerical results were compared with those of previous studies. To obtain a balance between the performance of the hydrofoil profile at zero-low and medium-high speed, we determined desirable ranges for various hydrofoil profile parameters including sweep angle, aspect ratio, and relative position of the shaft for non-retractable fins. Finally, tests were conducted using forced ship roll motion to determine the fin-induced anti-rolling moment and to test the optimized hydrofoil profile under real conditions.

零/低速尾翼稳定器受力建模和水翼剖面优化

摘要 尾翼稳定器已被广泛用于减少船舶中高速横摇运动。然而，传统鳍的减摇效率随着船速的降低而迅速下降。为了在整个速度范围内更有效地使用鳍片稳定器，我们推导出了零低速下的鳍片动力学。然后，通过实验验证了所提出的模型，并将数值结果与前人的研究结果进行了比较。为了在零低速和中高速下获得水翼剖面性能之间的平衡，我们确定了各种水翼剖面参数的理想范围，包括后掠角、纵横比和不可伸缩翅片轴的相对位置。最后，
