摘　　要：以工程应用为背景,从全局的角度提出了一种仿生微扑翼飞行器的动态分析与设计方法。在对鸟类的飞行参数进行统计分析的基础之上,拟合出扑翼飞行的仿生学公式,并据此进行了微扑翼飞行器的仿生学初步设计。根据仿生学结果设计了飞行器的传动布局、动力方案以及总体结构,并按照运动学分析、气动力分析以及动力学分析相结合的动态分析方法研究了微扑翼飞行器的动态特性。在动态分析的基础上进行了飞行参数的优化设计,使得微扑翼飞行器达到性能最佳。样机制作及风洞试验结果证明了这种方法的有效性与可行性。所得研究结论对微扑翼飞行器的设计、制作和应用提供了一定的理论依据。Flapping-wing micro air vehicles （FMAV） are new conceptual air vehicles that mimic the flying modes of birds and insects. A new dynamic analysis and design method for FMAV is proposed in the background of engineering application. Based on statistics and analysis of flying parameters of birds, the biomimetic formulas are brought forth and original FMAV design is carried out. According to the biomimetic results, the transmission layout, power scheme and total structure of FMAV are designed, and the dynamic properties of FMAV are studied by dynamic analysis method that includes kinematic, aerodynamic and structure dynamic analysis. Then the parameter optimization design is proceeded following dynamic analysis to reach the optimum performance of FMAV. Airplane prototype and wind tunnel experiments verify the effectivity and feasibility of this method, The results of research are helpful to the design, fabrication and application of FMAV.
