Firstly, through the theoretical calculation and simulation analysis of 6R spatial flapping-wing mechanism, the effect of different pole lengths on the "8" shape trajectory of wingtip is obtained. Then, a design method is proposed to improve the flight stability by adjusting the average dihedral angle of flapping-wing. The proposed mechanism is simulated by Adams software and the results show that the design of spatial flapping-wing mechanism is robust and steady, and the requirement of 90° phase difference between flapping angle and torsion angle is met %K 空间扑翼机构 %K 翼尖轨迹 %K 上反角 %K 相位差< %K br> %K spatial flapping-wing mechanism %K trajectory of wingtip %K dihedral angle %K phase difference %U http://journals.nwpu.edu.cn/jxkxyjs/CN/abstract/abstract6935.shtml
