In view of the application prospect of the hindwing of Anomala Corpulenta Motschulsky in the field of foldable Micro Aerial Vehicles (MAVs), this paper investigated the morphology, macro/microstructure of the hindwing, and the nanomechanical properties of the wing veins and the wing membrane. It revealed the variation of nanohardness and elastic modulus between different veins and different positions of the same wing veins. This paper established a 3D coupling model of the hindwing based on the principle of coupling bionics. This paper presents a simulation analysis of the structural statics (uniform load distribution) and aerodynamics (under different attack angles, flight velocities, and flapping frequencies). Two 3D coupling models (HW-I and HW-II) of the hindwing were discussed the deformation and flight aerodynamic performance of Workbenches and Fluent. On that basis, the bionic wing was generatively designed, and a 3D bionic wing (BioW) model was established using the generative design method. Simulation analyses were performed through structural statics and aerodynamics. The results showed that the stress distribution was relatively uniform and that the overall displacement deformation was minimal for the BioW model. Moreover, the BioW model had better flight efficiency and aerodynamic performance.
鉴于枯叶蛾后翅在折叠微型飞行器（MAV）领域的应用前景，本文研究了后翅的形态、宏观/微观结构，以及翅脉和翅膜的纳米力学性能。揭示了不同翅脉和同一翅脉不同位置之间纳米硬度和弹性模量的变化。本文基于耦合仿生学原理建立了后翅的三维耦合模型。本文对结构静力学（均匀载荷分布）和空气动力学（不同攻角、飞行速度和扑翼频率下）进行了仿真分析。讨论了两种后翅的三维耦合模型（HW-I 和 HW-II）在 Workbenches 和 Fluent 中的变形和飞行空气动力学性能。在此基础上，采用生成设计方法对仿生翼进行了生成设计，建立了三维仿生翼（BioW）模型。通过结构静力学和空气动力学进行了仿真分析。结果表明，BioW 模型的应力分布相对均匀，整体位移变形最小。此外，BioW 模型具有更好的飞行效率和空气动力学性能。
