| 摘 要： | 研究了一种形状记忆合金（SMA）丝驱动的仿生波动鳍推进器。在分析墨鱼鳍肌肉结构和运动机制的基础上，建立了鳍波动运动学模型，研制了基于SMA丝驱动柔性鳍单元的仿生波动鳍推进器，并进行了试验研究。结果表明，仿生推进器能实现与墨鱼鳍相似的柔性运动，波幅和推进力随SMA丝的驱动脉冲宽度的增加而增大，鳍波动推进力呈周期性变化，瞬时推力在驱动脉冲宽度80 ms时达到最大值180mN。

| Abstract: | A study about a biomimetic undulating fin propeller actuated by SMA wires was presented. Firstly, the structure and function of muscular hydrostats of cuttlefish fin were analyzed, and the kinematic model of the cuttlefish's fin undulatory motion was built. Secondly, a biomimetic undulating fin propeller actuated by SMA wires was developed. Finally, the hydrodynamic performance of the biomimetic propeller was tested. The results show that the flexible fin undulatory motion of biomimetic propeller is similar to fin of cuttlefish. The undulatory amplitude and thrust increases with increasing the actuating pulse width. The instantaneous maximum thrust is 180mN at actuating pulse width 80ms. |
