柔性复合型仿生鱼尾的设计与实验

Design and experiment of flexible compound biomimetic caudal fins

基于粗压电纤维复合材料(macro fiber composite,MFC)的特性,设计了一种柔性复合型仿生鱼尾及其驱动电源。采用有限元模拟和实验方法,研究仿生鱼尾的扭转运动模态以及实现仿生鱼尾的应用。仿真与性能测量结果表明:该柔性仿生鱼尾能够利用扭转振动模态模拟微型鱼的运动,最快游速达到320 mm/s。

According to the character of macro fiber composite（ MFC）,a flexible biomimetic caudal fin and its driven power supply were designed. The torsion mode of the caudal fin and its application were investigated by experimental study and finite element simulation. The simulation and measurement results indicate that the locomotion of micro fish is realized by the biomimetic caudal fin wored on the torsion mode. The fastest swimming velocity is 320 mm / s.
