摘要
设计了一款机翼对称拍打的X翼扑翼机构。采用曲柄滑块机构,将曲柄的圆周运动转化为直轴的直线往复运动,直轴再通过摇杆带动两侧机翼,从而实现机翼的对称拍打。制作了一台扑翼机构的样机,运用光学运动捕捉系统和风洞对该扑翼机构进行了运动测试,从扑翼机构的拍打角度幅值、拍打频率、产生的升力以及电机的运行状况方面分析了该扑翼机构的可靠性。通过对比试验,确定了一组合适的拍打角度幅值和翼面面积,使得该扑翼机构能够产生12.9 g的升力,验证说明clap-fling机制能够有效提高该扑翼机构的升力。
A X-wing flapping-wing mechanism with wings flapping symmetrically is designed.The crank slider mechanism is adopted to convert the circular motion of the crank into the linear reciprocating motion of the straight shaft,and the straight shaft drives the wings on both sides through the rocker to realize the symmetric flapping of the wings.A prototype of the flapping-wing mechanism is made,and the motion test of the flapping-wing mechanism is carried out using an optical motion capture system and a wind tunnel.The reliability of the flapping-wing mechanism is analyzed from the flapping angle amplitude,the flapping frequency,the lift generated,and the operating condition of the motor.Through comparative experiments,a set of suitable flapping angle amplitudes and wing surface areas are determined,so that the flapping-wing mechanism could generate 12.9 g of lift,and it is verified that the clap-fling mechanism could effectively improve the lift of the flapping-wing mechanism.
