仿鱼推进的实验研究

Experimental research of fish-imitating propulsion

模仿金枪鱼的摆尾推进方式,制作了单尾仿生机器鱼.实验测量了机器鱼的航行速度、阻力和系泊状态时尾鳍摆动产生的推力.针对单尾鳍摆动存在的机器鱼的摇艏问题,进一步设计出双尾鳍仿鱼推进器,并将其应用于小水线面双体船,制作了仿生双尾推进的实验平台.在水池中进行了实验研究,结果表明:仿生双尾推进不仅解决了单尾机器鱼游动时的鱼体晃动问题,而且还具有优良的推进效率和操纵性能.作为一种新型的仿生推进器,仿生双尾推进具有广阔的工程应用前景.

A robotic fish with single tail was made after the model of tuna.The speed and resistance of the robotic fish and the thrust that was produced by the tailfin of the robotic fish under the mooring condition were tested experimentally.To avoid the swing of forebody of robotic fish with only one tailfin,a kind of robotic fish with two tailfin was designed and is being used in small waterplane area twin hulls(SWATH).The experimental platform of two tailfin proprulsion was made.The experimental research of the d...
