摘要

无人机凭借灵活隐蔽的特性成为军事装备发展的焦点

其续航能力直接影响战斗力。无线充电是提升续航的主要手段

但实战中充电不对准问题严重制约了充电效率和战斗力发挥。为了解决这一问题

通过调研大量无线充电系统耦合器设计方案

结合分形几何在其他电磁领域的应用先例

创造性地提出一种具有Hilbert结构的无线充电耦合机构。通过建立数学模型分析偏移过程中的互感变化

利用有限元分析软件进行大量测试

确定了分形阶数

最后基于S-S电路进行了200W级的实验验证。研究结果表明

新提出的无线充电系统耦合器在对无人机其他性能参数不产生任何影响的前提下

仅通过改变耦合器线圈结构就实现了效率的全面提升

对无人机无线充电系统耦合器的设计具有较大研究意义。

Abstract

The unmanned aerial vehicles (UAVs) have become a focal point in military equipment development due to their flexibility and stealth characteristics

of which endurance capability is a key factor determining their combat effectiveness.Wireless charging is a major solution for enhancing the endurance capability of UAVs

yet the misalignment during charging in combat scenarios severely limits the charging efficiency and operational effectiveness.To resolve this challenge

a large number of design schemes of couplers for wireless charging systems are investigated

and a wireless charging coupling mechanism with Hilbert structure is proposed based on the applications of fractal geometry in other electromagnetic fields.The change in mutual inductance during misalignment is analyzed by mathematical modeling

and the extensive finite element analyses and simulations are conducted to determine the optimal fractal order.Finally

a 200W-level experimental validation is performed based on an S-S compensation circuit.The results demonstrate that the proposed wireless charging coupler achieves the comprehensive improvement in efficiency solely through structural modifications to the coil

without affecting other performance parameters of UAVs.This work holds significant research implications for the design of wireless charging couplers in UAV systems.
