摘要

摘要: 以蝉为研究对象,首先通过分析蝉翅翼在高速摄像机下的运动影像获得了其运动方程,然后建立了蝉翅翼的三维模型,并研究了基于Fluent软件的蝉翅翼周围流场数值模拟方法,最后模拟分析了三维蝉翅翼模型在不同运动参数(拍动频率、拍动幅值和最大扭转角度)下的平均升力系数和平均阻力系数.研究结果表明最大扭转角度对蝉翅翼气动力影响较大,因此在仿蝉扑翼飞行器的设计与操控中必须考虑扭转运动.

Abstract: A cicada was regarded as a research object. Firstly, its wing movement equations were gotten by analyzing the cicada's movement images from high-speed camera. Then, a three-dimensional model of the cicada's wing was established, and the numerical simulation method of flow field around the cicada's wing was studied based on Fluent software. Finally, the average lift and drag coefficients of the three-dimensional cicada's wing model were analyzed under the situation of different movement parameters (flapping frequency, flapping amplitude and maximum torsional angle). The research result shows that the maximum torsional angle greatly impacts the aerodynamics of cicada's wing, so the torsional movement must be considered in the design and manipulation of the flapping-wing maro air vehicles mimicking cicada.
