Design of the Electromagnetic Vibratory Mechanism for FMAV and the Research on Its Dynamics

  • 摘要: 设计了一种电磁振动式微扑翼机构,并建立了其非线性动力学模型.研究了不同电磁力激励下系统动态响应,获得了系统固有频率,并得出了方波和正弦半波电磁力驱动能够产生较大扑动幅度的结论.最后,研究了电磁振动式微扑翼机构机—磁耦合非线性系统动力学特性.研究结果表明,电磁振动式微扑翼机构适合采用正弦半波电压激励,而且通过改进结构,能够提高扑动的对称性和稳定性.

     

    Abstract: This paper designs an electromagnetic vibratory mechanism for Flapping-wing Micro Air Vehicle(FMAV),and presents its nonlinear dynamic model.Dynamic responses of the electromagnetic vibratory mechanism with different electromagnetic energizing force signals are investigated,its inherent frequency is obtained,and the conclusion that square wave and sine half-wave electromagnetic forces will generate large flapping amplitude is drawn.Finally,mechanics-magnetic coupling dynamic characteristics of the electromagnetic vibratory mechanism for FMAV are discussed.And the result shows that sine half-wave voltage is an appropriate energizing signal,and the flapping symmetry and stability can be increased if the structure is improved.
