摘　　要：中国轨道交通历经几代技术创新与发展,取得了令世界瞩目的成就。轮轨系统的黏着限制了轨道交通的进一步高速化,磁浮技术在轨道交通上的应用应运而生。“十三五”期间,中国开始研制600 km/h高速磁浮交通系统。高速磁浮列车运行速度为600 km/h,马赫数达到0.49,列车空气动力学性能急剧恶化,加之运行环境(车–轨间隙、两侧节流)的变化,呈现出与高速轮轨列车不同的气动特征,空气动力学问题成为高速磁浮列车设计研发的关键问题之一。本文探讨了600 km/h高速磁浮列车气动设计面临的技术挑战,提出了高速磁浮列车气动设计解决方案,介绍了我国600 km/h高速磁浮列车气动设计方案,展望了高速磁浮列车空气动力学未来研究方向。After several generations of technological innovation and development,China's rail transit has made remarkable achievements.The adhesion of the wheel rail system limits the further high-speed development of rail transit,and the application of the maglev technology in rail transit arises at the historic moment.During the 13th Five-Year Plan period,China began to develop the high-speed maglev transportation system with a speed of 600 km/h.The operational speed of the high-speed maglev train is 600 km/h and the Mach number reaches 0.49,and the aerodynamic performance of the train deteriorates sharply.Due to the change of the operational environment(train-rail gap,throttling on both sides)of the high-speed maglev train,the aerodynamic characteristics of the high-speed maglev train are different from that of the high-speed wheel-rail train.The aerodynamic problem has become one of the key issues in the design and development of the high-speed maglev train.In the present paper,the technical challenges faced by the aerodynamic design of the high-speed maglev train are discussed,and the solutions of the aerodynamic design of the high-speed maglev train are proposed.Then the aerodynamic design schemes of the China’s 600 km/h high-speed maglev train are introduced,and the future research fields of aerodynamics of the high-speed maglev train are prospected.
