Abstract

Lightning poses a serious hazard to ships navigating on the sea. Due to the large scale and complex structure of the platform, the lightning effect and experiment of the platform are special and complex. In order to obtain lightning strike attachment characteristics, attachment probability and electromagnetic environment in different areas of warship, the total differential lightning attachment analysis method based on zoning and layering was used to modify the additional areas and zoning of lightning attachment on warship. The characteristics of lightning strike attachment effect, lightning attachment probability and electromagnetic field strength on the whole surface of warship platform in different directions were obtained by simulation. Using lightning scaling model test of warship, the test validation and comparative analysis are carried out to verify the accuracy of the method and data, and to provide technical support for the protection and test of warship in lightning strong electromagnetic environment.

船舶雷电效应特性分析与试验评价

闪电对海上航行的船只构成严重的危险。由于平台规模大、结构复杂，平台的雷电效应和实验具有特殊性和复杂性。为了获得舰船不同区域雷击附着特征、附着概率和电磁环境，采用基于分区分层的全差分雷击附着分析方法，对舰船雷电附着的附加区域和分区进行修正。通过仿真得到了军舰平台全表面不同方向雷击附着效应、雷击附着概率和电磁场强度的特征。利用舰船雷电比例模型试验，进行试验验证和对比分析，验证方法和数据的准确性，为舰船在雷电强电磁环境下的防护与试验提供技术支持。
