The invention provides an optimal design method of a water jump robotic dolphin. The optimal design method comprises the following steps: adopting a slenderness ratio of 4.5 and/or a shoulder breadthposition to be positioned at 34-45% of a body length and/or selecting a crescent tail fin and/or adopting a sine swing amplitude modulation module and/or adopting a gravity center adjustment module. Propulsion of the robotic dolphin is realized through up-down swinging of the tail fin; real-time adjustment of the gravity center is realized by utilizing the gravity center adjusting module; and theup-and-down swing amplitude of the tail fin is realized through the sine amplitude modulation mechanism so that a forward propelling speed of a fish body is improved, problems that the existing robotic dolphin tail fin is small in up-and-down swinging amplitude range, large in swimming resistance, poor in maneuverability and flexibility and so on are effectively solved, and meanwhile, the water jump robotic dolphin optimized through the method is high in instantaneous speed of structural design, high in propelling efficiency and efficient in swimming performance.

    本发明提供一种跃水机器海豚的优化设计方法,优化设计方法包括采用4.5的细长比和/或肩宽位置位于体长的34~45%处和/或选用新月形尾鳍和/或采用正弦摆动调幅模块和/或采用重心调节模块。本发明运用尾鳍的上下摆动来实现机器海豚的推进,利用重心调节模块实现了重心的实时调节,通过正弦调幅机构来实现尾鳍上下摆动的幅度,从而改进鱼体向前推进的速度,有效解决了目前机器海豚尾鳍上下摆动的幅度范围小,游动阻力大,机动性、灵活性差等问题,同时经过本方法优化过后的跃水机器海豚,结构设计瞬时速度大,推进效率高,具有高效的游动性。
