摘要
列车质量与速度是影响运输能力与成本的重要因素,其优化选配对快速与高速列车尤为重要。本文在分析与比较提速列车质量计算的原则和方式方法以及相关的选择判别值的基础上,提出应从传统的侧重列车质量的方式转向侧重运行速度的方式,并最终确立第二临界坡度为推荐的最高速度(保有加速度)法与传统的计算速度法的选择判别值。文章最后通过具体提速客货列车质量的计算与分析,说明实际操作与应用。作者提出的列车质量计算的原则和方法也适用于高速列车。
Train mass and train speed are the important factors affected to transport capacity and traffic cost. Their optimized selection is more important to express train and high speed train.Based on analysis and comparison of the principle, method and form of train mass calculation and the correlative“ select judge value” for raising speed train,a change of particular attention from train mass to train speed is recommended in this paper,and the second critical gradient between the recommendatory maximum speed method (holding accelaration) and the traditional calculative speed method is established to the “select judge value”.Finally,through calculation and analysis of train mass for raising speed passenger and freight train ,the practical operation and use are illustrated.The recommendatory principle and method by the authors are also adapted to high speed train.
