In order to improve the flight performance of the flapping-wing aircraft, a two-stage foldable bionic flapping-wing mechanism is designed in this paper with reference to the flight motion characteristics of large birds. Firstly, the kinematic model of the flapping-wing mechanism is established by kinematic analysis, and the relationship equation between flapping angle and input angle and rod length is derived. Then, the three-dimensional model of the flapping-wing wing configuration is built in SolidWorks, and its output motion is obtained by ADAMS simulation to verify the theoretical analysis. The results show that the designed flapping-wing mechanism has a minimum transmission angle of Γ_min=48.6° and has good force transmission performance. The upper flapping limit of the inner wing is φ_max=45° and the lower flapping limit is φ_min=-5°; the upper flapping limit of the outer wing mechanism is φ_max=46° and the lower flapping limit is φ_min=-28°, which are consistent with the flight motion parameters of large birds.
