Abstract

Passively stabilized double-wing Flapping Micro Air Vehicles (FMAVs) do not require active control and exhibit good electromagnetic interference resistance, with significant research value. In this paper, the dynamic model of FMAV was established as the foundation for identifying flapping damping coefficients. Through a pendulum experiment, we ascertain the flapping damping of the damper using the energy conservation method. Besides, fitting relationships between the damper area, damper mass, and the moment of inertia are developed. The factors influencing the bottom damper damping are determined using correlation coefficients and hypothesis testing methods. Additionally, stable dampers are installed on both the top and bottom of the FMAV to achieve passive stability in simulations. The minimum damper areas for the FMAV were optimized using genetic algorithms, resulting in a minimum top damper area of 128 cm\(^{2}\) and a minimum bottom damper area of 80 cm\(^{2}\). A prototype with a mass of 25.5 g and a wingspan of 22 cm has been constructed. Prototype testing demonstrated that FMAV can take off stably with a 3 g payload and a tilt angle of 5\(^{\circ }\). During testing, the area-to-mass ratio of the FMAV reached 7.29 cm\(^{2}\)/g, achieving passive stability with the world’s smallest area-to-mass ratio.

被动稳定双翼扇动微型飞行器稳定阻尼器的优化研究
被动稳定双翼拍翼微型飞行器(FMAV)无需主动控制,具有良好的抗电磁干扰能力,具有重要的研究价值。本文建立了 FMAV 的动力学模型,为确定拍击阻尼系数奠定了基础。通过摆锤实验,我们利用能量守恒法确定了阻尼器的拍动阻尼。此外,还建立了阻尼器面积、阻尼器质量和惯性矩之间的拟合关系。利用相关系数和假设检验方法确定了影响底部阻尼的因素。此外,在 FMAV 的顶部和底部都安装了稳定阻尼器,以实现模拟中的被动稳定性。使用遗传算法对 FMAV 的最小阻尼面积进行了优化,结果是顶部阻尼面积最小为 128 cm(^{2}\),底部阻尼面积最小为 80 cm(^{2}\)。质量为 25.5 克、翼展为 22 厘米的原型机已经制作完成。原型机测试表明,FMAV 可以在有效载荷为 3 g、倾斜角为 5(^{\circ }\)的情况下稳定起飞。在测试过程中,FMAV 的面积-质量比达到了 7.29 厘米(^{2}/克),以世界上最小的面积-质量比实现了被动稳定。
