Simulation and Optimal Design of a Piezoelectric Bimorph Actuator for FlappingWing Micro Aerial Vehicle

Abstract

Abstract: In order to design a high-performance piezoelectric bimorph actuator for flapping-wing micro aerial vehicle, this paper synthesized orthogonal experiment and finite element direct coupledfield analysis simulation to optimize the actuator’s structure and geometric parameters. Different experimental schemes were achieved based on the orthogonal table. Through range analysis of the simulation results, the relative importance of factors influencing this actuator’s bending angle index was determined. Subsequently, the optimal scheme which can enhance the actuator’s performance was obtained. The simulation results show that the proposed method can increase the stroke angle significantly, which satisfies the design requirements of the flapping wing biomimetic MAV.

Key words: piezoelectric bimorph actuator, finite element method, orthogonal experiment, optimal design
