摘　　要：为了保证船舶航行安全,船用电子设备必须满足电磁兼容性要求.针对VHF通信频段辐射限值的特殊要求,利用三维电磁场仿真软件CST,从仿真角度对影响屏蔽结构屏蔽效能的因素进行分析,得出了一系列结论.利用所得结论,设计了具有合理结构参数和电磁参数的屏蔽装置,且经三维电磁场仿真软件验证其在VHF频段具有良好的屏蔽效能.For the special requirements of marine very high frequency （VHF） communication band radiation limitation, marine electronic equipment should satisfy the requirements of electromagnetic compatibility （EMC） in order to ensure the safety of navigation. The paper focuses on the use of 3D simulation software CST, from the view of simulation, studying the effects of electromagnetic parameters and structure parameters of shielding structure on shielding effectiveness （SE）. By the results obtained from the earlier study, the study proposes a suitable shielding structure, which has been verified to have a good SE at the VHF band.
