摘　　要：对昆虫飞行特性的研究不但可以认知动物生理,而更现实的目的在于为微型飞行器的设计提供思路。本文利用Fluent软件嵌入UDF函数研究了三维昆虫翅翼在不同控制飞行参数时的空气动力学性能,获得在不同的振型、拍动频率、攻角、平动转动相位差和飞行速度条件下翅翼受力作用。The research purpose of the amazing flying skills of the insect is not only the interest of the animal physiology hut to get the idea of the micro-aircraft design. The numerical simulation of the insect flight with UDF Function by CFD software avoids the 'moving boundary problem' which occurred definitely in the direct numerical simulation. We got some disci plines between insect flight and fling model, fling frequencies, phase difference between fling and rotate.
