6R两自由度空间扑翼机构设计与分析
Design and Analysis of 6R Spatial Flapping-wing Mechanism with Two Degrees of Freedom
摘要
Abstract
In this paper,by analyzing and improving the existing spatial linkage mechanism,a kind of 6R symmetric spatial flapping mechanism with two degrees of freedom is proposed for flapping-wing air vehicle.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.关键词
