鸟类通过翅膀的拍动和旋转运动提供飞行的驱动力和升力。本文研究了机器鸟翅膀的旋转幅度和旋转时间对飞行的状态影响,发现适当地选取这两个参数可以控制机器鸟在水平方向和竖直方向上的速度。本研究主要使用了两个工具:在不可压粘性流体中自主飞行的三维机器鸟和一个三维计算流体力学软件包,后者包含了浸入边界法(IBM)、体积函数法(VOF)、自适应多重网格有限体积法和游动与飞行的控制机制。
The birds provide the driving and lifting force of the flight through flapping and rotating wings. In this paper, we study the influence of the rotation speed and the rotation time of the machine on the flying state. We find that the proper selection of these two parameters can control the speed of the robot in the horizontal and vertical directions. Two tools were used in this study: three-dimensional robotic bird flying autonomically in incompressible fluid and a three-dimensional computational fluid dynamics software package that included immersion boundary method (IBM), volume function method (VOF), adaptive Multigrid finite volume method and control mechanism of swimming and flying.
