摘要

摘要: 针对外层空间物理环境模拟系统的技术要求,基于亥姆霍兹线圈的工作原理,采用一对匝数、边长、高度和厚度相同的共轴平行放置的正方形线圈构成了Helmholtz线圈,结合恒流源和单片机控制技术,设计了电磁场模拟系统.采用ANSYS Workbench有限元分析软件对正方形Helmholtz线圈的电磁场分布进行了数值模拟,重点考察了线圈X轴、Y轴和线圈表面附近的电磁场分布,在此基础上设计了线圈结构参数.对所设计的正方形Helmholtz线圈内部12个关键点的电磁场进行了测量,结果表明线圈内的磁感应强度和磁场均匀性能够满足环境模拟系统的要求.

Abstract: Considering the technical requirements of the space physical environment simulation system, a square Helmholtz coil was built by a pair of axis symmetric rectangular coils which had the same turns, side length, height and thickness, based on the principle of Helmholtz coils. Combining with the constant current source and MCU control technology, the electromagnetic field simulation system was designed. Adopting finite element analysis software ANSYS Workbench, the magnetic field distribution of the square Helmholtz coil was simulated, and the emphasis of the study was on the electromagnetic field distribution of the coil X-axis, Y-axis and near the surface of the coil. Based on the analysis results, the structure parameters of the square Helmholtz coil were designed. The magnetic flux density of 12 key points was measured inside the designed coil. The results show that the magnetic flux density and uniformity of the magnetic field inside the coil could satisfy the requirements of the space environmental simulation systems.
