摘　　要：针对小型扑翼飞行器柔性翼的特点,提出了一种利用欧拉方程结合有限元分析计算柔性扑翼上气动力的分析方法,并进行了样机推力测量实验.实验证明计算结果能很好地反映出扑动周期中不同时刻的推力特征.该方法既可以得到宏观上的推力、扑动阻力,又可以得到不同扑动参数下翼上各处的气动力分布,为柔性扑翼的设计优化提供帮助.A method of calculating the aerodynamic force on the flexible wing of mini flapping-wings was presented based on the Euler equation and finite element analysis. And the experiment was conducted to measure the thrust of a prototype. The results prove that the calculation can reflect the character of thrust during a flapping period. This method can gain not only the thrust and the flapping drag on the whole wing, and also the force map on different flapping characters. This is useful for the optimization design of the flexible flapping-wings.
