仿蜻蜓扑翼飞行器翅翼结构力学特性研究进展

摘要

总结了近年来蜻蜓翅翼和仿蜻蜓扑翼飞行器翅翼力学特性的研究进展,就蜻蜓翅翼形态结构与材料属性、翅翼结构力学特性、翅翼结构气动特性等方面进行了概述.根据近年发展现状,提出了关于该领域未来重点研究方向:翅翼形态结构方面,用更先进的观察仪器探究翅翼的细节特征;翅翼强度计算时,采用不同的材料属性以满足当前仿生翅翼材料的多样性;且在数值模拟计算中,计算模型需要趋于翅翼真实情况;并模拟出此前因受计算量限制而无法在计算模型中体现的翅翼细节;翅翼褶皱对翅翼结构力学特征的影响研究较少,相关领域亟待完善;此外本研究领域整体实验验证发展与数值计算相比还有一定差距,实验验证有待补足.%This paper focuses on the dragonflies and dragonflies-like FWMAV,mainly on the wings morphology,material attributes,mechanical properties and aerodynamics of wings.The development prospects and research trends of flapping structure are proposed,which are using more advanced observation instruments to explore the details of the wings to obtain the wing optimization inspiration,and in the simulation of wings strength,using different material properties to satisfy the diversity of the current bionic wings,and the computational modal should tend to the real situation of the wings.In addition,a lot of experimental verifications need to be made to catch the developing of computational simulations.
