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。
Taking engineering application as a background, a dynamic analysis and design method of bionic micro flapping wing aircraft is proposed from the overall view. Based on the statistical analysis of the flight parameters of birds, the bionics formulas of the flapping-wing flight are fitted and the preliminary design of the flapping wing aircraft is carried out. According to the results of bionics, the layout, power scheme and overall structure of the aircraft are designed. The dynamic characteristics of the micro-flapping aircraft are studied according to the kinematic analysis, aerodynamic analysis and dynamics analysis. Based on the dynamic analysis, the optimal design of flight parameters is made, which makes the micro flapping wing aircraft achieve the best performance. Prototype production and wind tunnel test results prove the effectiveness and feasibility of this method. The conclusion of the study provides a theoretical basis for the design, fabrication and application of flapping wing aircraft.
