摘要
基于大耳蝙蝠飞行时翅膀的飞行姿态和运动轨迹,对翅膀结构进行简化处理,模仿设计了一种二自由度的仿蝙蝠飞行器扑翼,能够实现上下扑动和收放动作.借助MATLAB/UG软件完成扑翼尺寸参数求解、结构三维建模、关键节点运动轨迹生成及上下扑动机构和收放机构的运动仿真分析.结果表明:节点角位移变化曲线连续不间断,未出现角度突变,不会造成瞬时冲击,翼尖关节之间运动不产生干涉,验证了扑翼运动的可行性,同时为后续优化设计提供理论依据.
Abstract
This article is based on the flight posture and trajectory of the wings of the large eared bat during flight,simpli-fying the wing structure and simulating the design of a two degree of freedom bat-like aircraft flapping wings,which can achieve up and down flapping and retracting movements.With the help of MATLAB/UG software,the flapping wing size pa-rameters are solved,the three-dimensional structure is modeled,the key node motion trajectory is generated,and the motion simulation analysis of the up and down flapping mechanism and the retracting mechanism is completed.The results show that the angular displacement curve of the joint is continuous without sudden change of angle,which will not cause instantaneous impact,and the movement between the wingtip joints does not interfere with each other,which verifies the feasibility of the flapping wing movement and provides a theoretical basis for the subsequent optimization design.
