蜻蜓翼微结构的弯扭性能分析

Analysis of Bending and Torsion Based on the Microstructure of Dragonfly Wings

  • 摘要: 本研究基于采集真实的蜻蜓翼样本,利用CAD软件和ANSYS软件建立仿蜻蜓翼的有限元模型并对其进行静力学分析,结果表明:蜻蜓翼的组合多边形结构模型起到了优化的作用,使得蜻蜓翼具备了刚性前缘、柔性后缘的结构特征,在一定程度上提高了蜻蜓的气动效率和飞行的稳定性;组合多边形结构模型在三种结构模型中的稳定性最好、结构更合理。

     

    Abstract: Based on the real samples of collected dragonfly wings, the finite element model of the dragonfly wings were established by software CAD and software ANSYS. The result that carried out by static analysis shows that the combined polygon models of dragonfly wing play a role in optimization, and the structure characteristics of the rigid front edge and flexible trailing edge can improve the aerodynamic efficiency of the dragonfly and flight stability. In the three structural models, the combined polygon model has the best stability, and the structure is more reasonable.
