摘要： 为了设计高性能的超微仿生扑翼飞行器压电双晶驱动器，提出了结合正交试验与压电场、应力场等多物理场直接耦合有限元法，对微驱动器的结构、几何参数进行优化.根据正交试验表设计有限元仿真分析试验，对试验结果进行极差分析，得到各影响因素对驱动器弯曲角度指标影响的主次顺序，并获得了提高压电双晶片驱动器性能的最优化方案.仿真结果表明，多物理场优化方法大幅度提高了扑动角度，满足超微扑翼飞行器的设计要求.

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
