摘要
磁浮列车与传统轮轨列车相比,由于没有接触网防护,更易受到雷击,将影响磁浮列车的行驶安全。开展磁浮列车雷击附着区域的研究,是进一步分析磁浮列车雷击直接效应和间接效应的基础。在国内外相关标准的基础上,基于有限元法数值仿真技术对磁浮列车雷击附着点和分离点划分开展仿真研究。研究结果表明:磁浮列车顶部曲率较大的位置容易遭受雷击,应将其划分为雷击附着区域;根据导向电磁铁上的场值分布,将车厢前后两侧的电磁铁部分区域划分为分离区域。研究结果为磁浮列车的雷电防护设计提供依据。
Compared with the traditional wheel-rail train, the maglev train is more vulnerable to lightning strikes due to the lack of contact net protection, which will threaten the driving safety of the maglev train. The research on the lightning zoning of the maglev train is the basis for further analysis of the direct and indirect effects of the lightning strike on the maglev train. Based on the relevant standards at home and abroad and the finite element method numerical simulation technology, the simulation research on the lightning strike attachment point and separation point division of maglev train is carried out. The research results show that the position with large curvature at the top of the maglev train is vulnerable to lightning strikes, which should be divided into lightning strike attachment areas. According to the field value distribution on the guide electromagnet, the electromagnet part of the front and rear sides of the carriage is divided into separate areas. The research results provide a basis for the lightning protection design of the maglev train.
