多层圆柱形磁屏体磁屏蔽特性研究
Research of Magnetic Shielding Efficiency of UltilayerCylindrical Shield
摘要
Abstract
Based on the electromagnetic shielding properties of high permeability ferromagnetic material and high conductivity materials,a three-dimensional finite element method analysis was performed to evaluate the magnetic characteristics of the cylindrical shield immersed in a steady uniform magnetic field generating by the copper coil on the iron core.The effects of the thickness of the magnetic shielding material,the number of layers of the cylindrical shell,and the excitation frequency on the magnetic shielding effectiveness were studied.The problem of optimal magnetic shielding method for different magnetic shielding materials such as the high permeability material and high electrical conductivity material is to be solved.The new technologies are explored to improve the efficiency of the magnetic shielding,which has important theoretical and applied significance in the electromagnetic compatibility problem.关键词
