摘要
从屏蔽效能的定义出发,得出了屏蔽系数与磁通量之间的关系,提出了利用椭球体模型对一般壳体的屏蔽系数进行计算的方法。利用模型化的方法分析计算了有限长圆柱壳的静磁屏蔽效能,并将推导的结果与严谨理论模型下的推导结果进行了对比,充分验证了椭球体模型计算的可行性。
The conclusion is based on the spheroid model which derives from the definition of shielding effectiveness and the relationship of shielding factor and flux. Through the modeling way, the shielding effectiveness of the general enclosure can be estimated, for instance, the limited length cavity. And the results conferred by this method are contrasted with precise academic model. By the contrast, the feasibility of the spheroid model is proved.
