摘　　要：以柔性金枪鱼月牙尾鳍为对象,对三关节机器鱼建立物理模型,并用MATLAB进行仿真。由模型对机器鱼的推进动力及推进速度进行研究,探讨了前进速度、横移和摇摆的幅度、频率及其相位差对柔性尾鳍推进性能的影响。该方法实现的运动仿真与真实的鱼的运动基本一致,速度随着摆动频率的降低而减小,随着相位差的减小而增加,摆幅对速度的影响很大。This paper takes flexible tuna crescent caudal as the research object,establishing a physical model of the three joint robotic fish with the method of MATLAB simulation,propulsion motive power and the advancing speed are researched by the model of robotic fish.Besides,the influences of speed,transverse sliding,swaying amplitude,frequency and phase difference on flexible caudal propulsion properties are discussed.The realization of the motion simulation is basically the same as the real fish sport,the speed decreases as swing frequency reduces,and increases as the phase difference decreases,pendulum deflection have a big effect on speed.
