摘要

蝴蝶是一种独特的飞行昆虫,可以以10-15赫兹的低拍动频率飞行。因此,它在飞行时消耗的能量很少。然而,低频翼拍的机理尚未得到充分的解释。在这项工作中,发现同步的拍打和扭转运动增强了向上和向下划水的正升力。建立了蝴蝶前翼模型并进行了实验,研究了扑动和扭转运动对前翼推力和升力产生的影响。提出了主动扑动和被动扭转机构。研究了不同范围的扑动和机翼的扭转角度。实验结果表明,大的对称扭转角[-75°,75°]具有独特的3周期重复扑动力,在大多数时间内产生0-0.06 N的正升力,推力波动在±0.10 N的范围内强烈波动。这种同步的正升力产生的扑动和扭转运动是自然界中蝴蝶飞行的一种解释,揭示了蝴蝶如何以如此低的扑动频率提升自己。

Effects of the Butterfly Forewing Flap-and-twist Motion on the Generation of Thrust and Lift
—A butterfly is a unique flying insect that can fly at a low flapping frequency of 10-15 Hz. Therefore, it consumes little energy while flying. However, the mechanism of low-frequency wing beat has not been thoroughly explained. In this work, it was found that the synchronized flap-and-twist motion enhances the positive lift during both upstroke and downstroke. Models of butterfly forewings were made and tested to investigate the effects of flapping and twisting motions on the generation of thrust and lift. The active flapping and passive twisting mechanisms are proposed. Different ranges of flapping and twisting angles of the wings were investigated. The experimental result shows that the large symmetric twist angle [-75°, 75°] has a unique 3-cycle repetition of flapping force, which generates positive lift in a range of 0-0.06 N most of the time, with strong thrust fluctuations in a range of ±0.10 N. This synchronized flapping and twisting motion with positive lift generation is one explanation for butterfly flight in nature and reveals how butterflies can lift themselves with such a low flapping frequency.
