针对低黏着接触条件下车轮滑行所引起的列车纵向冲动问题,文章建立了“1+1”编组2万吨重载列车-轨道垂纵耦合动力学模型,对比分析电制动工况下不同轮轨接触状态对2万吨列车纵向冲动的影响,分别计算了车轮发生滑行位置和电制动力载荷大小对纵向冲动的影响规律。结果表明,在电制动运行工况下,当列车施加100%电制动力时,列车在湿润、油污和冰雪接触条件下均检测到了车轮滑行,在25%~75%电制动工况下列车仅在冰雪接触条件下检测到了车轮滑行;车轮滑行导致了车钩力的波动,特别是中部机车发生车轮滑行时会引起其前、中、后部车钩力较大幅度波动,并增大中部机车前部车辆压钩力,严重影响列车的平稳运行;随着制动力的降低,低黏着接触状态下的车轮滑行对最大车钩力的影响明显减小。
In response to the longitudinal impulse issue caused by wheel slip under low-adhesion contact conditions
this paper established a vertical-longitudinal coupled dynamics model for a 20
000-ton heavy-haul train in a '1+1' formation. A comparative analysis was conducted to examine the impact of different wheel/rail contact states on the longitudinal impulse of the 20
000-ton train under electric braking conditions. The impact of wheel slip position and electric braking force loads on the longitudinal impulse was calculated separately. The results indicate that under electric braking operation
wheel slip was detected for the train under wet
oily and icy contact conditions when the train applies 100% electric braking force. In contrast
under 25%~75% electric braking conditions
wheel slip was only detected when the train under icy contact conditions. Wheel slip led to fluctuations in the coupler forces
particularly when wheel slip occurred in the middle locomotive
causing significant fluctuations in the coupler forces at the front
middle
and rear of the middle locomotive and increasing the coupler force at the front of the middle locomotive
thereby seriously affecting the smooth operation of the train. As the braking force decreased
the impact of wheel slip on the maximum coupler force reduced significantly under low-adhesion contact conditions.
