摘　　要：由于海洋的环境复杂且气候多变,因此船舶在航行过程中,会因为洋流的影响而导致船舶的航行受到一定影响,进而产生多自由度运动。而横摇运动作为影响最大的一种运动方式,对船舶的安全航行造成极大的隐患。因此伴随着仿生学的发展,仿驼背鲸改进减摇鳍的出现,可以协助船舶在应对横摇的过程中起到降低运动幅度的作用。为了更好地应用仿驼背鲸改进减摇鳍,发挥其在抵抗海洋环境干扰的作用,本文从升力系数数值计算入手,对其展开深入分析,完善其鳍角升力系数变化量,为船舶的安全航行提供更为丰富的理论依据。Due to the complex ocean environment and variable climate,ships may experience certain impacts on their navigation due to the influence of ocean currents during navigation,resulting in multi degree of freedom movement.As the most influential mode of motion,roll motion poses great risks to the safe travel of ships.Therefore,with the development of bionics,the appearance of humpback whale like fin stabilizers can help reduce the motion amplitude of ships in the process of rolling.Therefore,in order to better apply the humpback whale like fin stabilizer to play its role in resisting the ocean responsible environment,this paper will start with the numerical calculation of lift coefficient,carry out in-depth analysis on it,and improve its fin angle lft coefficient variation,bringing more abundant theoretical basis for ships'ocean navigation.
