铁路应用空气动力学标准理解和认识

Interpretation of the Aerodynamics Standards for Railway Application

铁路应用空气动力学标准是国内第一部铁路行业的空气动力学系列标准,为推进铁路行业相关人员和机构对标准的深入理解,促进铁路行业的空气动力学标准化应用研究,通过对比分析BSEN14067系列空气动力学标准,从发布的意义、规范的重点内容、后续的补充完善等方面对标准进行分析,重点介绍了符号与单位、隧道空气动力学效应、隧道空气动力学要求和试验方法以及列车空气动力学性能数值仿真规范等标准的四个组成部分。

Railway ApplicationAerodynamics is China′s first series of standards about aerodynamics in the rail-way industryTo promote the deep understanding of relevant personnel and institutions in the industry about this standard and enhance the research of the application of aerodynamic standardization in the railway industry,this paper has mainly introduced the four components of symbols and units,tunnel aerodynamic effects,tunnel aerodynamic requirements and test methods,and specification for numerical simulation of train aerodynamic through a comparative analysis of this series of standards and the BSEN 14067 series of standards of aerodynamics and a discussion of the significance of the release of this series of standards,main contents of specifications,followup supplement and improvement,etc.
