| 摘 要： | 使用列车空气制动仿真方法获得空气制动系统特性, 通过列车动力学仿真方法分析了3万t列车在多机车不同步条件下紧急制动和常用制动时车钩力, 提出了大秦线3万t重载组合列车的可行性编组。分析了从控机车在各种滞后时间情况下, 列车常用和紧急制动的最大车钩力的变化特点。研究结果表明: 平道常用全制动工况下, 从控二机车滞后时间比从控一机车滞后时间对车钩力影响更大, 从控机车滞后于主控机车5 s时, 最大车钩力增加了80.2%;平道紧急制动工况下, 从控一机车滞后时间对车钩力影响更大, 从控机车滞后于主控机车5 s时, 最大车钩力增加了335.9%;从控机车滞后时间控制在4.1 s以内, 车钩力可以控制在许用范围内。
