摘　　要：为研究胸鳍攻角对仿生机器鱼升潜运动的影响,制定机器鱼升潜运动控制规则,分析了升力产生的机制和影响因素,建立了机器鱼胸鳍摆动数学模型,根据机器鱼胸鳍几何模型,应用Gambit建立了机器鱼胸鳍二维网格模型,应用Fluent仿真,分析了不同攻角下机器鱼升力阻力差,确定胸鳍在来流速度为0.5 m/s的水动力环境下做周期摆动时的最佳攻角为20°左右。To research the influence of attack angle on the bionic robo-fish in dive motion,the robo-fish dive motion control rules was made,the lift with generation mechanism and influence factors was analyzed,and the swing model of pectoral fin was estab-lished. According to the geometry model of pectoral fin,the pectoral fin of robo-fish two-dimensional grid model was established by ap-plying the software of Gambit. And applying Fluent software simulation,the robo-fish lift and resistance difference under different at-tack angle was analyzed,the pectoral fin optimal angle of attack is about 20＆#176; at flow velocity of 0.5 m/s in hydrodynamic environment with doing periodic swing was determined.
