    摘要:

    为了实现鸟类飞行过程中翅膀的折弯效果,以平面四杆机构为基础,设计一套能实现主动折弯并具有急回特性的扑动-折弯运动模型。采用ADAMS对其进行动力学仿真分析,结果显示该模型具有优良的动力学性能;采用ADAMS与XFlow联合仿真方法对其进行气动特性分析,结果显示该模型具有优良的气动特性;同时,得到翅膀的扑动速度对扑翼的气动特性起着至关重要作用的结论。

    Abstract:

    In order to realize the bending effect of the wings during the flight of birds, a set of flutter-bending motion model was designed which could realize active bending and had a quick return characteristic based on the planar four-bar mechanism. The dynamic simulation analysis shows that the model has excellent dynamic performance. The aerodynamic characteristics of the model were analyzed by ADAMS and XFlow co-simulation.The results show that the model has excellent aerodynamic characteristics. At the same time, it is concluded that the flapping speed of the wing plays a crucial role in the aerodynamic characteristics of the flapping wing.
