Abstract The aerodynamic efficiency is low, the energy consumption is high for flapping to micro flapping wing
used traditional mechanism. The bionic flapping wing driven by piezoelectric materials effectively integrates flapping
mechanism and the wings. It is not only to save weight but also to be the task of deformation and strong adaptive ability,
high aerodynamic efficiency, low energy consumption characteristics of mechanism. It is to establish finite element model
of piezoelectric flapping wing by PCL language. The structure simulation of piezoelectrically driven bionic flapping wing
is carried out with the size of the aerodynamic force of the experimental data. The piezoelectrically driven bionic flapping
wing is developed by using simulation results. The studies show flapping frequency of bionic flapping wing is improved
obviously after using piezoelectric actuator.The piezoelectric patches can effectively control wing bending and torsion deformation,
and help to improve aerodynamic efficiency of flapping wing.
