摘要: 随着武器系统平台的电磁环境日益复杂, 对所装载的武器电磁兼容性(EMC)要求越来越高。针对依据GJB151A-1997要求进行鱼雷EMC试验时, 测试项CE102和RE102试验曲线均超出规定极限值的问题,为了使武器平台与鱼雷能够更好的匹配工作, 通过分析多平台使用条件下全雷系统的EMC改进案例, 对雷内电子组件的干扰源进行排查、定位, 得到雷内电磁辐射及传导频率特性, 并分别对鱼雷系统内部电缆、电源、雷内电子组件和壳体结构等采取屏蔽、滤波和接地等有效改进措施, 最终顺利通过该2项测试, 为后续鱼雷的EMC设计提供参考。Abstract: In an electromagnetic compatibility(EMC) test of torpedo according to the standard GJB151A-1997, the test curves of CE102 and RE102 exceed the prescribed limit value. In order to solve this problem and to better match the weapon platform with torpedo, this study analyzes a case of EMC improvement of the whole torpedo system under the condition of multi-platform operation, investigates and locates the interference sources of the electronic components in the torpedo, obtains the frequency characteristics of the electromagnetic radiation and conduction in the torpedo, and separately improvements the cable, power supply, electronic components and shell structure of the torpedo by means of the measures, such as shielding, filtering and grounding. Finally, the torpedo successfully passes these two test items. This study may facilitate the EMC design of torpedo.
