摘要本文是对列车空气动力学进行广泛综述的两部分论文的第二部分。第1部分详细描述了列车周围的流场，并确定了一些流动区域。并讨论了侧风和流动约束的影响。基于这一基本认识，本文接着讨论了现代列车设计和运营中的一些问题。这些问题包括空气动力学阻力和能耗、轨旁结构的空气动力学载荷、列车滑流中乘客和轨旁工作人员的安全、列车下方道碴的飞行、列车在大风中倾覆以及与列车通过隧道相关的问题。简要的结论得出的必要性，建立一个一致的基于风险的框架的空气动力学效应。
Abstract This paper is the second part of a two-part paper that presents a wide-ranging review of train aerodynamics. Part 1 presented a detailed description of the flow field around the train and identified a number of flow regions. The effect of cross winds and flow confinement was also discussed. Based on this basic understanding, this paper then addresses a number of issues that are of concern in the design and operation of modern trains. These include aerodynamic resistance and energy consumption, aerodynamic loads on trackside structures, the safety of passengers and trackside workers in train slipstreams, the flight of ballast beneath trains, the overturning of trains in high winds and the issues associated with trains passing through tunnels. Brief conclusions are drawn regarding the need to establish a consistent risk based framework for aerodynamic effects.
