The wing is one of the most important parts of a bird's locomotor system and is the inspiration origination for bionic wing design. During wing motions, the wing shape is closely related to the rotation angles of wing bones. Therefore, the research on the law of bone movement in the process of wing movement can be good guidance for the design of the bionic morphing wing. In this paper, the skeletal posture of the peregrine falcon wing during the extension/flexion is studied to obtain critical data on skeletal posture. Since an elbow joint and a wrist joint rotate correlatively to drive a wing to flex/extend, the wing skeleton is simplified as a four-bar mechanism in this paper. The degree of reproduction of wing skeleton postures was quantitatively analyzed using the four-bar mechanism model, and the bionic wing skeleton was designed. It is found that the wing motions have been reproduced with high precision.
翅膀是鸟类运动系统最重要的部分之一，也是仿生 wings 设计的灵感来源。在翅膀运动过程中，翅膀形状与翅膀骨骼的旋转角度密切相关。因此，研究翅膀运动过程中骨骼运动的规律可以为仿生变形翅膀的设计提供很好的指导。本文研究了游隼翅膀在伸展/弯曲过程中的骨骼姿势，以获得骨骼姿势的关键数据。由于肘关节和腕关节协同旋转驱动翅膀弯曲/伸展，因此本文将 wing 骨骼简化为四杆机构。利用四杆机构模型对 wing 骨骼姿势的再现程度进行了定量分析，并设计了仿生 wing 骨骼。结果表明，翅膀运动得到了高精度的再现。
