摘要
舱体屏蔽效能的试验评价是验证车载复杂系统抗电磁脉冲加固性能的重要环节。为了定量估计试验设计和结果评定所引入的不确定度, 以高空电磁脉冲为背景, 分别从频域/时域测试方法选择、测试频点设置、合格曲线设计和超差点的处理等几个要素, 研究了舱体电磁脉冲屏蔽效能的验证评价方法。针对车载复杂系统典型舱体屏蔽效能较低的特点, 针对不同屏蔽效能提出了一簇合格曲线,并基于二阶谐振系统模型, 定量估计了频点设置准则、合格曲线、超差点处理准则所引入的不确定度,为舱体屏蔽效能的试验设计与数据分析提供了方法与支撑, 同时定量分析也可作为不确定度估计的基础。
Abstract
Evaluating the shielding effectiveness of cabins is important for verifying the susceptibility of systems against high altitude electromagnetic pulses. To quantitatively estimate the uncertainty introduced by experiment designs and data analysis, the method of evaluation is studied, which focuses on the selection of frequency or time domain measurement, the determination of test frequencies, the design of pass/fail curve, and the criteria to deal with unqualified points. A group of pass/fail curves for cabins with low shielding effectiveness are proposed. Based on the approximation of two order resonance systems, the uncertainty introduced by test frequencies, pass/fail curve, and the criteria are estimated, which provide sustainment for the experiment design, data analysis and the uncertainty estimation for evaluating the shield effectiveness of cabins.
