摘　　要：针对目前飞行器结构复杂、效率低下及动作单一等问题,设计一种新型仿生扑翼飞行机构,仅通过单驱动装置即可实现机构扑翼的扑动、折叠、扭转等运动。依据生物尺度率设计扑翼机构的结构尺寸并对机构参数进行优化;通过SolidWorks构建仿生三维模型并基于ANSYS Workbench对扑翼机构进行有限元分析,得到扑翼齿轮组、曲柄、主翼杆等主要部件的总形变、应力、等效应变及主、副翼动力学运动参数,为仿生样机研制提供理论支持。In view of the complex structure,low efficiency and single action of present aircrafts,a new type of bionic flapping-wing flight mechanism is designed,which can realize 3-DOF flapping,folding and torsion by single motor.According to the biological scale rate,the structure dimension of the flapping wing aircraft is designed,and its mechanism parameters are optimized.The bionic 3D model is constructed by SolidWorks and the finite element analysis of the flapping wing aircraft is analyzed based on ANSYS Workbench to gain the total deformation,stress、equivalent strain and dynamic motion parameters of flapping wing aircraft,which provides theoretical support for the optimization of the prototype.
