According to the structural characteristics of bird wings, this paper presents a new type of flapping wing mechanism with single degree of freedom. The mathematical model of this structure has been established by this study. The left and right flapping angles of the mechanism are obtained through this simulation. The change rules of the left and right flapping angular velocities and the left and right flapping angular accelerations of the left and right rocker arm instantaneous flapping angular difference mechanism are also simulated by this model. This model lays a theoretical foundation for the dynamic characteristics of the mechanism. This study also makes a experimental plane. In this study, a high-speed camera was used to record the motion process of the experimental plane. The experimental results show that the test aircraft in this paper can realize the required movement of bionic wings. This study provides some theoretical and engineering guidance for the design of flapping wing mechanism.
