摘要
为了保证船舶的航行安全,船用电子设备应满足电磁兼容性要求。针对船舶甚高频(VHF)通信频段辐射限值的特殊要求,从箱体谐振、电源线谐振以及缝隙谐振等方面研究了电子设备在该频段产生电磁骚扰的机理;利用三维电磁场仿真软件,从上述三方面对船用电子设备VHF频段电磁骚扰转移技术进行分析研究,得出了一系列结论。将结论应用于实际船用电子设备电磁兼容性设计中,缩短了设计周期,节省了设计成本,提高了产品性能。
For navigation safety, marine electronic equipment has to comply with EMC requirements. The phenome na of cabinet resonance, power line resonance and gap resonance are studied with reference to the special require ments of marine VHF communication band radiation limitation. And measures to reduce EMI by shifting the reso nant frequencies are analyzed by using a 3-D electromagnetic field simulation plied to designing marine electronic products. The experiences show that the performances of products with reduced design time and costs.
