摘要
列车保有加速度的选择直接影响列车质量与列车速度的合理匹配。通过分析和计算列车保有加速度与保有功率系数、列车比功率的关系以及列车质量与最高速度之间关系的基础上,提出设计或引进牵引动力时,应选择较高的列车保有加速度,而既有机车牵引时,容许选用较小的列车保有加速度,并推荐了具体数值范围。
Option of train holding acceleration bears directly on the reasonable coordination of train mass and train speed.Based on analysis,study and calculation carried out regarding the relations of train holding acceleration with the coefficient of holding power and the train specific power as well as between the train mass and the maximum speed.The paper suggests that higher values of train holding acceleration be selected in making designs or importing locomotives or motor train units and that lower values of train holding acceleration be selected when operating existing locomotives.Here numeral values or ranges of train holding acceleration are recommended by the authors.
