摘　　要：基于气-固两相流理论,采用CFD数值模拟技术系统地研究和分析了快速磁浮列车的积雪特性,重点研究了降雪量、侧风、车速及路基结构对列车悬浮架雪粒子堆积的影响。研究结果显示,侧风工况下,列车底部积雪现象普遍严重,尤其是悬浮架区域,其积雪量甚至可达车底各部件总积雪量的50%~70%。相对于10 m桥梁工况,路基工况减弱了列车底部区域的积雪效应。根据研究结果,提出了三种防积雪方案并进行对比分析,分析表明列车裙板具有良好的防雪效果;通过工程化应用及装车验证,验证效果良好。Based on the gas-solid two-phase flow theory,this study systematically investigates and ana-lyzes the snow accumulation characteristics of fast maglev trains using CFD numerical simulation tech-nology,with a focus on the effects of snowfall intensity,crosswind,train speed,and embankment structure on snow particle accumulation in the levitation frame of the train.Results indicate that under crosswind conditions,snow accumulation beneath the train is significantly severe,particularly in the levitation frame area,where the accumulated snow can account for 50%to 70%of the total snow vol-ume across all undercarriage components.Compared to a 10-meter bridge scenario,the embankment scenario reduces the snow accumulation effect in the undercarriage region.Based on these findings,three anti-snow accumulation solutions are proposed and comparatively analyzed.The analysis demon-strates that the train skirt exhibits effective snow prevention performance.The proposed scheme has been successfully applied in engineering practice and validated through on-vehicle verification,yielding favorable results.
