Structural Design and Simulation Analysis of Bionic Mechanical Fish

以鲹科鱼类作为仿生研究对象,通过分析鲹科鱼类的游动机理,以高机动性、低扰动性等性能作为设计目标,设计出三关节串联式尾鳍推动系统,解决了仿生机械鱼的结构设计、质量分布等问题,使其可以保持稳定的游动姿态,实现灵活推进。进一步对仿生机械鱼结构进行仿真分析,研究了仿生机械鱼在特定条件下受到水流冲击力时的作用反馈,证明该结构具有较高的游动效率和推动力。

This paper takes the carangidae as the bionic object and study its swimming mechanism,such as high mobility and low disturbance.According to this mechanism,a three joint tandem tail fin propulsion system is designed in order to solve the structural design,mass distribution and other problems of the bionic mechanical fish,with a view to achieving stable swimming posture and efficient propulsion.Furthermore,the bionic mechanical fish is simulated and analyzed,and the feedback of the bionic mechanical fish under the impact force of water flow in specific conditions is studied,which verifies that the structure has high swimming efficiency and high propulsion.
