Dynamic analysis of piezoelectrically driven flapping wing

Abstract

Abstract The micro flapping wing using the traditional flapping wing mechanism has the disadvantages of low aerodynamic efficiency and high energy consumption. The bionic flapping wings driven by piezoelectric materials can effectively combine the two main systems of flapping wings and wings. It not only has the task of reducing weight but also has the characteristics of strong deformation ability, high aerodynamic efficiency, and low energy consumption of mechanism. The structure simulation of piezoelectrically driven bionic flapping wing was carried out to use aerodynamic experimental data of the same size of flapping wing. The piezoelectrically driven bionic flapping wing was developed by using the simulation results. The studies show flapping frequency of bionic flapping wing has been improved obviously after using the piezoelectric actuator. The piezoelectric patches can effectively control the wing bending and torsion deformation, which is helpful to improve aerodynamic efficiency of the flapping wing.
