摘　　要：通过尺度律分析初步确定仿生翼的基本参数。运用计算流体动力学(CFD)方法,对仿生翼进行数值模拟,计算出气动力特性和使飞行器能够在空中悬停的拍打频率。基于Pro/E的微扑翼机构系统动力学分析,研究了运动副的约束反力,为选择和设计轴承,以及计算零件的强度等提供了依据。By the foundation of the scaling laws, some parameters of bionic wing are determined. Using Computational Fluid Dynamics （CFD） to conduct the numerical simulation of the bionic wing, the aerodynamic characteristic and the flapping frequency at which the micro vehicle will hover in air were figured out. Utilizing Pro/Engineer, the forces acting on each crucial kinematic pair are obtained. These forces should be provided for the choosing and designing of mechanical elements.
