中文摘要:
      建立了仿生拍动推进推力和效率的测量平台,通过电机的转动扭矩、转动角速度及推进力计算得到仿生推进系统的推进效率。对本课题组研制的组合仿生无人水下航行器中柔性双尾鳍模型进行了测量与分析,结果表明柔性尾鳍推进时小摆幅摆动运动效率要高于大摆幅运动;双尾鳍推进方式在小摆幅模式下无论在推进力还是在效率方面都要优于单尾鳍。最后根据模型实验数据,优化了双尾鳍推进的运动参数,并用于优化UUV性能。
英文摘要:
      Thrust efficiency of biomimetic propulsion actuator affects significantly the performance of bionic unmanned underwater vehicle (UUV). Several kinds of caudal-fin-type actuator for a hybrid bionic UUV were designed. In order to test these actuators, based on a water channel, a platform was built for measuring thrust force, motor's rotational speed and torque. Then, thrust efficiency suggested by Lighthill can be calculated. A series of experimental measurements were conducted and some results were obtained. Comparing with rigid-tail fin actuator, the flexible-tail fin actuator has better performance in both thrust force and thrust efficiency. For flexible-tail actuator, flapping with small amplitude and high frequency provides same thrust force as the flapping with large amplitude and low frequency. But the former efficiency is higher than the latter. In small flapping amplitude mode, the thrust force and thrust efficiency of double parallel tail fins are better than that with single tail fin. Finally, the movement parameters of actuator with double tail fins were optimized based on experimental results,which were adopted in performance optimization of UUV.
