舰船雷电波形与防护试验研究北大核心CSCD

舰船电子信息及武器系统密集,随着使命任务和活动海区的不断拓展,在海上执行任务的舰船面临的雷电危害日益突出。舰船具有船体尺度大、平台上桅杆和各类突兀的天线众多等复杂结构特点。针对雷击对舰船作用波形特性不明及舰船雷电试验如何开展等难点和关键问题,采用基于吸引面积的分析方法,建立了雷电通道、舰船和主桅系统一体化模型,分析雷电对舰船的作用效应,获得了舰船雷电效应波形的特性及电磁环境参数,提出了舰船不同分区和试验波形选择,确定了舰船雷电防护试验项目和试验程序,提出关键项目试验方法,并开展了验证试验,为提升舰船在雷电强电磁环境下的生存力和战斗力提供技术支撑。

Study on Navy Ship Lightning Waveform and Protection Test

Ships have dense electronic information and weapon systems. With the continuous expansion of missions and active sea areas, ships performing missions at sea are facing increasingly prominent lightning hazards. Ships have complex structural characteristics such as large hull size, numerous masts and various abrupt antennas on the platform. Aiming at difficulties and key problems such as the change of waveform characteristics and complex test after lightning acts on ships, using the analysis method based on the attraction area, the integrated model of lightning channel, ship and main mast system is established, the effect of lightning on ship is analyzed, the characteristics and parameter changes of ship lightning effect waveform are obtained, the selection of different ship zoning and test waveform are put forward, the test items and test procedures of ship lightning protection are determined, and the test methods of key items are proposed. The verification test is carried out to provide technical support for improving the survivability and combat effectiveness of ships in the lightning strong electromagnetic environment.
