摘　　要：中低速磁浮列车目前主要采用高架运行方式,由于车辆悬浮架、轨道结构型式与传统轮轨系统完全不同,当列车在高架线路运行时,冰雪天气对列车的影响较大。文章通过调研分析中低速磁浮列车实际冰雪运行情况,开展列车冰雪运行工况仿真的数值建模,分析了侧风、车速与轨道型式等因素对列车冰雪堆积的影响,针对现有车辆与轨道结构型式组合而成的4种应用场景,开展了对比分析,提出具体优化建议,最后根据实际应用情况与分析结果,提出了工程化应用方案和相关设计要点。分析所得结论对中低速磁浮列车防冰雪技术认知提升和工程化应用具有很好的指导意义。Medium-low speed maglev trains typically operate in elevated mode and have unique suspension systems and track structures that are different from traditional wheel-rail systems.As a result,these trains are more susceptible to the impacts of snowy and icy weather when running on elevated tracks.The article conducted research and analysis on the actual operation of medium-low speed maglev trains in icy and snowy conditions.A numerical model was developed to simulate the train's operating conditions in these weather conditions,and factors such as crosswind,speed,and track type were analyzed for their impact on ice and snow accumulation on the train.Four application scenarios based on existing vehicle and track structure combinations were compared and analyzed,and specific optimization suggestions were proposed.Finally,based on the actual application conditions and analysis results,engineering application plans and related design points were presented.The conclusions drawn from the analysis had significant guiding significance for improving understanding of anti-icing technology for medium-low speed maglev trains and its engineering application.
