摘要
高速列车最高速度的分级研究,可为我国高速列车的设计、引进、制造、运用以及维修等提供界定速度等级和型谱的基础性依据。在分析近代国际铁路高速列车技术发展态势的基础上,结合我国高速列车发展的现状和未来方向,通过对已有200-400km·h^-1列车相关数据分析和比功率计算,提出为满足最高速度要求,应选择较大保有加速度,并在计入回转质量系数的列车保有加速度为0.05~0.1m·s^-2的条件下,推荐中国高速列车最高速度的分级采用三级方案:T级(最高速度400km·h^-1)、Ⅰ级(最高速度330km·h^-1)和Ⅱ级(最高速度250km·h^-1)。这种速度分级是基于最高速度还有上浮空间,且可基本涵盖全高速区范围。当前研究重点是优化开发Ⅰ级和Ⅱ级高速列车,并为T级高速列车做准备。
The classification study on top speed of high speed train will support greatly the definition of speed grade, which is useful to the design, import, manufacture, service and maintenance, and provides the important foundation for the drawing of train spectrum. Based on the study of international advanced technology and combining with the development actualities and application future of our high speed train, the paper analyzes the relational data about the existing 200-400 km· h^-1 trains and calculates their power/weight ratio, and puts forward, under meeting top speed requirement, that the higher holding acceleration train should be selected. And under condition of 0. 05-0. 1 m · s^-2 holding acceleration considering the rotary mass coefficient, three classes of top speed for high speed trains in China are suggested. They are class T (top speed of 400 km · h^-1) , class Ⅰ( top speed of 330 km · h^-1) and class Ⅱ (top speed of 50 km·h^-1 ). The classification is based on the top speed and still has some reserved room, and basically covers all high speed scopes. The paper indicates that the present day research should first develop class Ⅰ and class Ⅱ high speed trains and should be prepared for class T high speed train.
