Effect of Aerodynamic Wings on Lift Force Characteristics of High-Speed Maglev Train

  • 摘要:

    磁悬浮列车高速运行时受到较大气动升力作用,尤其是尾车向上的气动升力较大,易使悬浮性能恶化,甚至导致悬浮控制系统失效,影响列车的乘坐舒适性及运行安全性,因此亟待开展高速磁悬浮列车的尾车升力特性研究及改善工作. 对开展过风洞试验的高速磁悬浮列车进行数值模拟计算,得到的列车表面压力系数与风洞实验数据吻合较好,并加装气动翼改善高速磁悬浮尾车气动升力,研究了气动翼角度、数量对尾车气动性能的影响. 研究结果表明:仅安装一个气动翼时,其自身的气动升力随角度的增加而减小,但尾车气动升力则呈现先减小后增大的规律,气动翼角度为12.5° 时尾车升力最小,与原始磁悬浮列车相比气动升力系数减小3.9%,气动翼及尾车气动阻力略有增加;以气动翼与车体切线角度保持不变为基准在尾车安装多个12.5° 气动翼,不同位置气动翼的气动阻力基本相同,气动翼数量增加后尾车气动阻力随之增大;不同位置气动翼的气动升力存在差异,向鼻尖方向气动翼的气动升力递减,尾车气动升力随气动翼数量增加先减小后趋于稳定;各方案中安装2个气动翼的磁悬浮列车气动性能相对更优,与原始磁悬浮列车相比尾车气动升力减小4.6%,整车阻力仅增加1.4%.
