摘要
为研究长鳍扭波推进的水动力性能,在对尼罗河魔鬼鱼形体构造、游动模式研究的基础上,研制了一种仿生长鳍扭波推进航行器。该推进器能逼真地模仿尼罗河魔鬼鱼长背鳍的扭波运动模式,产生强劲的水动力。在水池中开展扭波推进模型航行试验,得到了航行速度与扭波频率的关系曲线。该曲线表明:扭波推进模型的航行速度与扭波频率成正比。提出了一种测量机器鱼鱼鳍推水功率的实验方法,实验结果表明:扭波长鳍的推水功率与扭波频率的3次方成正比。
Based on the research of the swimming modes and phystcal constructm~ ut t_tyllL^la^llu,＇, niloticus fish（GNF）, a bionic robot-fish was build which can simulate the torsional wave propulsion of GNF realistically and produce a strong propulsion force so as to explore the hydrodynamic mechanism of torsional wave propulsion of the long-based flexible fin. A series of swimming experiments was made with this bionic robot-fish model in a pool. The results show that the speed of the model is proportional to the wave＇s frequency. The method of measuring the power of fish fin to push water in swimming was proposed. The power of fish＇s fin was proved to be proportional to the cubic of the wave＇s frequency.
