摘要
单尾鳍推进的仿生鱼会产生周期性的、较大幅度的侧向力,使得鱼体产生横向振荡和偏摆,不利于游动的稳定性。为了消除侧向力的影响,提出一种双尾鳍摆动推进的策略,通过双尾鳍的对称摆动来抵消摆动时产生的侧向力。研制了形状记忆合金丝驱动的仿生双尾鳍推进器,并通过仿真和实验的方法对双尾鳍的推进性能进行分析。
Bionic fish propelled by single tail fin will produce periodic and more substantial lateral force, making thefish produce lateral oscillations and yaw, is not conducive to swimming stably. In order to eliminate the effects of lateralforce, a double tail fin swimming strategy was proposed. The lateral forces generated during the swing can be counteractedby swing symmetrical double tail fin. A thruster based on bionic double tail fin actuated by shape memory alloy wires wasdeveloped. The propulsion performance of the d thruster based on bionic double tail fin was analyzed by the method of simulationand experiment.
