摘　　要：在仿鸟扑翼飞行器的设计中,扑翼的气动特性分析对样机的制作、试飞和控制有重大影响。分析了鸟类扑翼飞行扑动特点,给出了一种简易"挥拍-扭转-弯曲折叠"多自由度运动模型,利用XFlow软件在低雷诺数非定常流场情况下对多自由度扑翼飞行器进行三维数值仿真模拟,求解在扑翼扑动作用下的周围绕流空气的流场特性,分析飞行器扑翼截面形状、扑动频率和来流速度对流场的影响。给出的仿真结果可以对扑翼飞行器的研制和改进提供理论和技术支持。The aerodynamic characteristics analysis of flapping-wing is of great significance to the design, manufacturing and control of the aircraft. In this paper, a simple motion model of multiple-Degrees-ofFreedom（multi-DOF） of ＂swing-torsion-bending and folding＂ is established by analyzing the flight characteristics of bird-like flapping wing. The flapping-wing air vehicle of multi-DOF is numerically simulated in the case of unsteady flow at low Reynolds number by XFlow software. The effects of flapping wing shape, frequency and inflow on surrounding air are analyzed. The simulation results provide theory and technique supports for the flapping-wing air vehicle＇research and development.
