摘要

为满足极弱磁测量设备便携小型化的发展要求，提出了一种新型头盔形可穿戴自屏蔽线圈的设计方法。采用边界元法（BEM）建立了自屏蔽线圈的解析计算模型，实现了高均匀磁场自屏蔽线圈的优化设计。引入加权系数，精确控制目标场点的选取。计算得到HWSC内部的最大MF偏差和外部的最大MF衰减偏差分别为2.28%和16.08%，与不考虑耦合的线圈相比，外部MF衰减降低了69.15%。实验结果表明，HWSC的最大内部衰减偏差为2.86%，最大外部衰减偏差为17.84%。该方法为磁屏蔽器件向小型化、便携化方向发展的过程中，内部线圈的优化设计提供了新的思路。

Design Method of a Novel Helmet-Shaped Wearable Self-Shielding Coil

To satisfy the development of portable and miniaturized extremely weak magnetic measuring devices, a novel helmet-shaped wearable self-shielding coil (HWSC) design method is proposed in this article. An analytical calculation model of HWSC is established by the boundary element method (BEM), which achieves the optimum design of self-shielding coils with a high homogeneous magnetic field (MF). Weighting coefficients are introduced to precisely control the selection of target field points. The calculated maximum MF deviation inside the HWSC and maximum MF attenuation deviation outside are 2.28% and 16.08%, respectively, which reduces the external MF attenuation by 69.15% compared with the coil without considering coupling. The experimental results show that the maximum internal deviation and external attenuation deviation of HWSC are 2.86% and 17.84%, respectively. This approach provides new ideas for the optimal design of internal coils in the development of magnetically shielded devices toward miniaturization and portability.
