基于扑翼式飞行器机构的研究

Research on Flapping Wing Aircraft Mechanism

本文通过对鸟类骨骼和四种传统扑翼式飞行器机构的研究,针对单曲柄双摇杆传动机构扑翼运动的不对称性,从而影响运动的稳定性,以及双曲柄双摇杆传动机构虽然扑翼运动对称,但是只能简单的做上下扑动动作,而鸟类飞行翅膀还伴随着扭转动作,基于以上问题,本文设计出一可以模仿鸟类飞行时复杂扑翼运动的飞行器,扑翼既可上下扑动又可扭转,并分析了该飞行器的传动原理,利用三维软件Pro/E给出了扑翼式飞行器扑翼机构的三维模型,为未来全方位模仿扑翼运动提供一定技术支持。

In this paper,through the study of bird skeleton and four kinds of traditional flapping-wing aircraftmechanism,aiming at the asymmetry of flapping -wing motion of single crank and double rocker transmissionmechanism,the stability of flapping-wing motion is affected,and the flapping-wing motion of double crank anddouble rocker transmission mechanism is symmetrical,but it can only do up and down flapping movement simply,while birds Based on the above problems,this paper designs an aircraft which can imitate the complex flapping-wing movement of birds in flight. The flapping-wing can flutter up and down as well as twist. The transmissionprinciple of the aircraft is analyzed. The three-dimensional model of the flapping-wing mechanism of the flapping-wing aircraft is given by using the three-dimensional software Pro/E. It will provide some technical support for future all-around imitation of flapping wing.
