昆虫飞行高升力机理的研究

随着仿生扑翼飞行机器人的微型化,当扑翼飞行机器人达到昆虫量级的时候,任何复杂的运动系统都将面临难以实现的问题.本文从研究现有比较成熟的昆虫飞行高升力机制出发,指出了现有"昆虫飞行高升力机理"研究成果中存在的一些问题,用"柔性楔形效应"对昆虫飞行高升力机理进行了合理解释,提出"柔性楔形效应"是昆虫前飞过程中获得很大升力的主要原因.用"柔性楔形效应"解释昆虫飞行高升力机理,翅翼运动的模拟方式有可能只需在自适应变形状态下施以简单的节律运动.该结论将对仿生扑翼飞行机器人的研究产生重要影响.

Research on the High Lift Mechanism in Insect Flight

As the miniaturization of the bionics flapping aerocraft, the complex locomotion system will be confronted with the problem that is difficult to come true when its weight and the size are as same as the insect. Beginning with the study of the modern biologic flying theory, this paper points out the shortcoming of the existing production about the high lift mechanism in insect flight. At the same time, it points out that the primary reason of the high lift in insect forward flight is the flexible wedge-effect, which can explaine the theory of the organism flight reasonably. Ac- cording to the high lift mechanism in insect flight explained by the flexible wedge-effect, simulating the locomotion of the wing is exerted some simple rhythmic locomotion in the state of the self-adaptability distortion. This conclusion will influence the development of the bionics flapping gerocraft.
