摘要
电磁驱动的微扑翼飞行器翼端拍打振幅受到驱动电压、磁感应强度、电流角频率等因素的影响。为了探究上述三个因素对微扑翼飞行器翼端拍打振幅的影响规律,提出一种新型电磁驱动器方案,并建立电磁场中微梁振动模型,为验证电磁驱动器方案的可行性及进一步探究相关因素对微梁振动的影响规律,设计开展电磁驱动的微梁振动试验。结合理论振动模型与试验结果,得到驱动电压、磁感应强度、电流角频率对于梁端拍打振幅的影响规律,研究结果对于后续微扑翼飞行器电磁驱动器的研究发展具有一定的指导意义。
The wing-tip amplitude of flapping-wing micro air vehicles actuated by electromagnetic force is affected by driving voltage,magnetic flux density and current angular frequency. In order to explore the influence rule of the above three factors on wing-tip amplitude,a new type of electromagnetic actuator scheme is proposed and the vibration model for micro-beam vibration in electromagnetic field is established. To verify the feasibility of the electromagnetic actuator,and further study on effect rule of related factors on vibration of microbeam,vibration tests of micro-beam actuated by electromagnetic force are designed. Combined with theoretical vibration model and experimental results,the influence rule of driving voltage,magnetic sensing intensity and current angular frequency on beam-end amplitude are obtained,the results of this study are of guiding significance for the subsequent researches on electromagnetic actuation of flapping-wing micro air vehicles.
