摘要
为模仿海鸥飞行,设计一种两段式仿生扑翼机构。建立单曲柄双摇杆扑动机构的简化模型,分析满足两侧摇杆偏差角最小时各杆长的经验公式。利用SolidWorks和ADAMS软件建立扑翼飞行器的动力学模型,分析内外翼的运动参数和飞行器整体的位姿变化。结果表明:在相同杆长条件下,曲柄中存在夹角的机构在减少左右摇杆相位差角方面更具优势;两段式仿生扑翼机构可实现翅翼慢频率扑动和展向折弯。仿真结果验证了机构设计的合理性,为扑翼飞行器后续的研究提供参考。
In order to imitate the seagull flying,a two stage bionic flapping wing mechanism was designed.The simplified model of single crank double rocker mechanism was established,and the empirical formulas of each rod length satisfying the minimum deviation angle of two rockers were analyzed.The dynamics model of flapping-wing aircraft was established by using SolidWorks and ADAMS software.The motion parameters of internal and external wings and the overall position and attitude changes of the aircraft were analyzed.The results show that the mechanism with angle between the crank and the left rocker has more advantages in reducing the phase difference angle between the left and right rockers under the same length of the rod.The mechanism design is reasonable,which provides reference for flapping-wing aircraft in the following study.
