Abstract

Flapping wing deformation influences the aerodynamics of insect flight. This deformation is dictated by the dynamical properties of the insect wing, particularly its vibration spectra and mode shapes. However, researchers have not yet developed artificial insect wings with vibration spectra and mode shapes that are identical to their biological counterparts. The goal of the present work is to develop artificial insect wings that are both isospectral and isomodal with respect to real insect wings. To do so, we characterized hawkmoth Manduca sexta wings using experimental modal analyses. From these results, we created artificial wings using additive manufacturing and heat molding. Between artificial and real wings, the first two natural frequencies differ by 7% and 16% respectively, with differences of 16% and 131% in gains evaluated at those natural frequencies. Vibration modes are similar as well. This work provides a foundation for more advanced wing design moving forward.
动态相似人工昆虫翅膀的设计
扑翼变形影响昆虫飞行的空气动力学特性。这种变形是由昆虫翅膀的动力特性决定的,特别是它的振动谱和模态振型。然而,研究人员还没有开发出具有与生物翅膀相同的振动谱和模态振型的人工昆虫翅膀。本研究的目标是开发与真实昆虫翅膀具有等谱和同模的人工昆虫翅膀。为此,我们使用实验模态分析对Manduca sexta的翅膀进行了表征。根据这些结果,我们使用增材制造和热成型制造了人造翅膀。在人工机翼和真实机翼之间,前两个固有频率分别相差7%和16%,在这些固有频率下评估的增益差异为16%和131%。振动模式也是相似的。这项工作为今后更先进的机翼设计奠定了基础。
