摘要
依据孔缝耦合机理和导电衬垫转移阻抗理论,建立了适用于不同类型屏蔽门的广义屏蔽设计模型,并以机柜为研究对象,对衬垫类型、层数等因素进行了分析,得到了屏蔽效能的计算值.通过机柜屏效测试,验证了设计模型和分析的正确性,得出了一些有工程参考价值的结论.
A generalized design model applying to different electromagnetic shielding doors is established with the theory of aperture coupling and transfer impedance of the conductive gasket. Taking the cabinet as a research object and considering the main influential factors, such as gasket types, the number of layers, the analysis and programme simulation are made and the calculated value of shielding effectiveness is obtained. By testing the shielding effectiveness of the cabinet, the rationality of the designing model is proved with the valuable conclusions for engineering obtained.
