摘要/Abstract

摘要： 高速磁浮列车的气动升力是列车悬浮和导向控制的关键气动载荷，以五辆编组高速磁浮列车为研究对象，利用数值计算方法分析高速磁浮列车气动升力的分布规律，研究列车气动升力的影响因素，结果表明，头车和尾车的气动升力分布最为恶劣，车体底部结构对气动升力的分布影响很大，车体底部与轨道梁之间的气隙流场特性决定了气动升力的分布规律。根据高速磁浮列车气动升力的分布规律，提出一种通过控制气隙空间的空气流量来控制列车气动升力的方法，数值计算和风洞试验表明，气动升力控制方法能够显著改变列车的气动升力，实现列车气动升力的精确控制，指导高速磁浮列车的气动升力工程设计。

Abstract: The aerodynamic lift force is one of the key aerodynamic loads for the suspension and guidance system of high-speed maglev trains (HSMT). The computational fluid dynamics (CFD) method is adopted to study the lift force distribution laws of HSMT with five carriages and the influencing factors are discussed. The results show that the distribution laws of the lift force of the leading car and trailing car are worst. The bottom structures of the HSMT has a serious influence on the lift force and the air gap flow field between the bottom and the railway determines the distribution of the lift force. A method of controlling train lift force by controlling the air flow in the air gap space is proposed according to the lift force distribution laws. The CFD and wind tunnel test results show that the method can precise control the lift force, which may be used to the engineering design of lift force of the HSMT.

Key words: aerodynamic lift force, maglev train, flow control, wind tunnel test
