摘要
目前微型扑翼飞行器(MAV)在军事以及民用方面都正在普及,发挥着越来越重要的作用。扑翼生物在飞行过程中展现了其气动效率高、动作敏捷、可稳定悬停等优点。本文以扑翼昆虫为研究对象,提出了一种新型的扑翼飞行器,设计了一种可变旋转轨道半径的扑翼机械结构模型和控制系统。进行旋转半径变化时,芯片控制变轨电机转动,进而改变变位滑块距离旋转中心的位置,通过传动机构最终表现为扑翼拍动幅度的改变。针对设计的机械结构,进行坐标系建立和表达式的推导,同时利用XFlow进行流体仿真试验,通过基准试验、双翼变幅值仿真流体试验以及单翼变幅值仿真流体试验,得到相应的结论,验证了可变拍幅扑翼飞行器模型的合理性和可行性,为后续研究及样机制作提供了数据支持。
At present,micro air vehicles(MAVs)are being popularized in both military and civilian fields and are playing an increasingly important role.The flapping wing organism shows its advantages of high aerodynamic efficiency,quick action,and stable hover during flight.In this paper,by studying flapping wing insects,a new type of flapping wing aircraft was proposed,and a mechanical structure model and control system with variable rotating orbit radius were designed.When the rotating radius changed,the chip controlled the rotation of the variable rail motor and then changed the position of the displacement slider from the rotation center,which was finally represented by the change in the flapping amplitude of the flapping wing through the transmission mechanism.According to the designed mechanical structure,the coordinate system was established,and the expression was derived.At the same time,XFlow was used to carry out fluid simulation tests.Through the benchmark experiment,the fluid simulation test of the variable amplitude of the two wings,and the fluid simulation test of the amplitude of the variable single wing,the corresponding conclusions were obtained,and the rationality and feasibility of the variable-amplitude flapping wing aircraft model were verified.It provided data support for follow-up research and prototype production.
