摘　　要：介绍了与高速列车有关的空气阻力、空气压力脉冲以及侧向风力所产生的倾覆力矩等3个空气动力学方面的问题。分析和讨论了列车交会时所产生的空气压力脉冲、影响压力脉冲强度的因素以及空气压力脉冲的测量方法,并介绍了计算静态和动态抗倾覆稳定性的检验公式和方法。Three aerodynamics points related with high speed trains——air resistance,air pressure pulse and overturning moment caused by lateral air force——are described.The air pressure pulse appeared during two trains going across one another,and factors affecting the pressure pulse intensity and measurement method for air pressure pulse are analyzed and discussed.The check formula and method to calculate static and dynamic overturning stability are described.
