摘　　要：以蓝鳍金枪鱼为蓝本,进行了仿鱼尾推进小型水下航行器方案设计与模型制作,包括设计主体外形、主体结构及安装形式、传动机构、尾鳍形状等。在水池中开展了自航实验,测定了尾鳍的摆幅、频率、形状及刚度对航速的影响,结果表明在相同条件下提高尾鳍摆动频率或增大尾鳍摆幅,能提高水下航行器的速度;当采用柔性尾鳍时,航行器的速度明显增加。A small underwater vehicle applying fish swimming mechanism is designed and developed based on the bluefin tuna. The hull shape, main body construction, drive gear and caudal fin shape are carefully designed. A self-pwpelled experiment is conducted in the towing tank. The effects of flapping amplitude, frequency, shape and rigidity on the speed are studied. It can be concluded that the speed of the vehicle is impwved by the flapping frequency and amplitude. When the flexible fin is applied, the speed is significantly impwved.
