基于融合算法的长方形均匀磁场线圈设计

Design of Rectangular Uniform Magnetic Field Coil Based on Fusion Algorithm

摘要: 传统的长方形亥姆霍兹线圈已经难以满足实际的工程需求，针对这一迫切的问题，本文提出了一种基于PSO-GWO融合算法和目标场点相结合的均匀线圈设计方法。本文首先需要明确线圈的待优化参数，并引入高阶求导和磁场偏差率来构建目标函数；然后，采用PSO-GWO融合算法来对目标函数进行寻优求解；最后，得到优化后的线圈参数之后，本文根据线圈参数建立相对应的有限元仿真模型，并对均匀度和均匀体积进行了比较分析，验证了优化结果的可信度。

Abstract: The traditional rectangular Helmholtz coils are no longer capable of meeting the practical engineering demands. In response to this urgent issue, this paper proposes a uniform coil design method based on the PSO-GWO fusion algorithm and the target field point method. Firstly, this paper needs to clarify the parameters to be optimized for the coil and introduces high-order derivatives and the magnetic field deviation rate to construct the objective function. Then, the PSO-GWO fusion algorithm is adopted to optimize and solve the objective function. Finally, after obtaining the optimized coil parameters, this paper establishes the corresponding finite element simulation model based on the coil parameters and compares and analyzes the uniformity and uniform volume to verify the credibility of the optimization results.
