摘要
使用中间层电路模型(ILCM)近似仿真分析屏蔽门对屏蔽室屏蔽效能的影响,对模型理论公式进行了推导和仿真,得出密封条式屏蔽门的屏蔽效能与影响参数之间的关系,为选择更适合屏蔽门密封的材料提供理论依据,并选择了两种材料进行对比验证,证明了推导出的关系是正确的,同时也预测了密封条结构的屏蔽室的屏蔽效能。仿真结果表明,我们选择的密封条式结构和材料能够满足屏蔽室的要求。
The intermediate level circuit model (ILCM) is used to simulate and evaluate the influence of shielding door on shielding effectiveness (SE). Through the theoretical equation derivation, the con'elations between SE of shielding door with seal and influential parameters are obtained to provide theoretical basis on choice of seal material. Finally, the verification is carried out by comparing two different materials, which proves that foregoing theoretical derivation is correct. Simultaneously, SE of shielding door with seal structure is predicted.
