摘　　要：本文研究了电子设备产生的静电放电抗扰度问题,针对电子设备结构处理中的孔缝优化方法进行分析,利用Matlab/Simulink建立孔缝机壳屏蔽模型和带孔缝机壳屏蔽接地模型,通过对模型进行仿真研究,提出了孔缝优化设计方法.静电放电防护整改实际案例的测试结果表明,论文所给方案极大地提高了电子设备静电放电抗扰度等级,研究结果对电子设备静电放电防护具有一定的工程应用价值.In this paper, the problem of electrostatic discharge immunity caused by electronic equipment is studied. Based on the analysis of the holes in the electronic equipment structure, the shielding model of the slotted grounding model of the slotted casing are established by using Matlab/Simulink. The simulation design of the model is putforward. The results of the two electrostatic discharge protection rectification cases showthat the proposed scheimproves the electrostatic discharge immunity level of electronic equipment. The research results haveapplication value for electrostatic discharge protection of electronic equipment.
