摘　　要：对设备机箱内部某串口电路受外界强电磁脉冲干扰所引起的信号完整性问题进行了研究,基于场路结合的仿真分析方法,从空间电磁耦合现象和电路信号干扰效应这两个方面对强电磁脉冲干扰进行了完整的系统分析,发现电磁干扰可导致内部电路出现逻辑电平翻转等扰乱效果,并提出了有效避免电磁干扰的措施。In order to make relatively accurate analysis for electromagnetic interference problem occurred in interior circuit ofequipment chassis, this paper adopts an analysis method based on field-circuit co-simulation to realize electromagnetic interferenceeffect analysis for chassis the interior circuit by taking chassis interior circuit as an example. It is discovered that the electromag-netic interference may cause the interior circuit to produce some disturbance effects such as logic level flip, which provides a refer-ence for research on operating characteristics of circuit in electromagnetic interference environment.
