| Abstract: | This paper is based on the"Sparrow"MAV(Micro Air Vehicle)flapping wing mechanism developed by Delaware University.Due to the inertia of the wing and the periodic fluctuation of the aerodynamic force with time during the operation of the flapping wing mechanism,it is easy to cause a certain fluctuation in the speed of the motor.The magnitude of motor speed fluctuation will directly affect the vibration impact force of each sports subsidiary,thus affecting the service life of the mechanism.The theoretical and simulation analysis of the flapping wing driving mechanism is carried out in this paper.It is found that the appropriate increase of the flexible device in the system can reduce the fluctuation of motor speed to a certain extent.At the same time,the vibration and impact force of each motion supplement is simulated and analyzed before and after the increase of the flexible device.It is found that the vibration and impact force of each motion supplement decreased to a certain extent after the flexible device is added.The reduction of impact force can also improve the vibration and noise in flight to a certain extent.Therefore,the flapping wing aircraft is more suitable for the practical application environment. |
