在无线电能传输技术在无人机领域实际应用中，无人机降落时由于定位精度以及停靠时的控制精度存在误差，会导致停靠位置不准确而产生偏移，由于无人机本身体型较小，耦合机构的尺寸也会较小，此时存在的偏移会导致耦合机构的耦合程度降低，进而导致无线电能传输系统工作效率的降低，影响系统的正常工作。因此，为了提高系统的抗偏移特性，需要对无人机无线充电系统的耦合机构进行合理的设计以及优化。本文通过结合无人机结构特性，在用线量一致的约束条件下分析对比不同耦合机构的耦合特性，设计适用于无人机的最佳耦合机构；然后对耦合机构参数进行以M/l为优化目标的轻量化优化；最后通过仿真和实验验证了该耦合机构优化方法的可行性。

n the practical application of wireless power transmission technology in the field of UAVs, when the UAV lands due to the positioning accuracy and the control accuracy of docking there is error, will lead to inaccurate docking position and shift, due to the small size of the UAV, the size of the coupling mechanism will also be smaller, the offset at this time will lead to a decrease in the coupling degree of coupling mechanism, which in turn leads to the reduction of the efficiency of the wireless power transmission system, affecting the normal operation of the system. Therefore, in order to improve the anti-offset characteristics of the system, it is necessary to reasonably design and optimize the coupling mechanism of the UAV wireless charging system. In this paper, the coupling characteristics of different coupling mechanisms are analyzed and compared under the constraint of consistent line usage in combination with the structural characteristics of UAVs, and the optimal coupling mechanism suitable for UAVs is designed. Then, the parameters of the coupling mechanism are optimized for lightweight with M/l as the optimization goal. Finally, the feasibility of the coupling mechanism optimization method is verified by simulation and experiment.
