摘　　要：为了分析仿生机器鱼的推进模式并预测水下推进性能,对其水动力特性开展研究。基于鲆鲽鱼型双驱动仿生机器鱼和波动推进理论,研究入流速度和波动频率对自推进性能的影响。对胸鳍在不同攻角下的升阻比进行数值计算,最佳攻角为20°。通过研究掌握了影响运动性能的主要因素,确定了计算自推进速度的数值方法,改进了机器鱼波动推进模型。研究结果显示,尾部波动频率是最关键参数,对仿生机器鱼的推力和启动响应速度有直接影响。In order to analyze the propulsion pattern of the bionic robotic fish and to predict the underwater propulsion performance, its hydrodynamic characteristics are investigated. Based on flounder dual drive bionic robotic fish and wave propulsion theory, the effect of inlet velocity and fluctuation frequency on self-propulsion performance is studied. The lift-to-drag ratio of the pectoral fins is calculated numerically for different angles of attack, the optimum angle of attack is 20°. Through this study, the main factors affecting the motion performance are mastered, the numerical method for calculating the self propulsion speed is determined, and the robotic fish undulation propulsion model is improved. The tail fluctuation frequency is the most important parameter, which has a direct impact on the thrust and starting response speed of the bionic robotic fish.
