水下柔性鱼形机构原理及单尾鳍板水动力试验研究

柔性鱼形机构是模拟鱼类运动的一种仿生机械系统。对鱼类运动的观察与研究 ,实质上是寻求水域中最优推进形式的过程 ,是工程优化设计的途径之一。在研究及优化柔性鱼形机构时涉及到水动力学及控制模型的问题 ,因此取出鱼形机构的尾鳍部分进行敞水试验 ,既能为有关模型的建立提供依据 ,更重要的是对鱼形机构的可行性进行论证

Study on principle of marine flexble fish-like mechanism and hydrodynamic experiment of single fin

The flexible fish-like mechanism, which stimulates the movement of fish, is a kind of machine system of biomechanics. Fish in the specific aquatic environment have formed the most optimal morphologic shape and locomotion mode through the evolvement and natural selection of thousands of years. Therefore, observations and researches on the movement of fish are a process to seek the best mode of propulsion and are also a approach to the optimization of engineering design. The paper deals with the complex hydrodynamic and control model in the optimization and study of the flexible fish-like mechanism. Open water experiments have been conducted with the tail fin of the mechanism, which may provide the foundation for the establishment of the model involved and demonstrate the feasibility of the fish-like mechanism.
