摘要
为了设计仿蜻蜓扑翼飞行器,对现有曲柄摇杆机构进行改进,提出了一种基于单曲柄轴的仿蜻蜓双翅翼空间扑翼机构。采用理论分析和数值仿真相结合的方法,研究了该扑翼机构的运动学特性。采用ADAMS对设计的仿蜻蜓扑翼机构进行仿真分析,结果表明所设计的扑翼机构可有效实现两侧运动完全对称,并且机构运动流畅平稳,机构扑动幅值达到了仿蜻蜓扑翼飞行器设计要求,且满足前后翼扑动角相位相差90°。
In this paper,by analyzing and improving of the existing crank rocker mechanism,the double wings spatial wing mechanisms imitating a dragonfly flapping wing air vehicles based on single crank shaft is proposed in order to design dragonfly like flapping wing air vehicles.And the kinematic characteristics of the flapping wing mechanism are studied by combining theoretical analysis with numerical simulation.The mechanism designed is simulated and analyzed by ADAMS and the results show that the flapping wing mechanism designed can effectively achieve complete symmetry of motion on both sides,and the mechanism motion is smooth and stable and the amplitude of the mechanism flapping reaches the design requirements of the imitates dragonfly flapping wing aircraft,and the phase difference of flapping angle between front and rear wings is 90°as required.
