摘　　要：在全国铁路建设的不断发展下,高舒适性成为了列车运行质量的重要指标。但对于整个制动过程,如电制动淡出阶段及停车阶段的舒适度关注不足。本文基于地铁列车常用制动工况,为综合评价舒适度,引入制动平均冲击、瞬时冲击、减速度变化率等参数指标,并在此基础上提出了一种舒适度优化的制动控制方案。通过对优化前后的控制参数进行地铁列车制动试验,获得了如下试验结果:三个阶段中,列车的舒适度分别提高了15.85%、58.23%和58.39%。试验表明所提出的舒适度优化制动控制方案在实际应用中取得了显著的效果。With the continuous development of rolling stocks in China,high comfort has become an important index for assessing the quality of train operation.However,there is insufficient attention to the comfort level during the entire braking process,including stages such as electric brake fading and parking.The comfort index is evaluated based on average braking jerk,instantaneous jerk,and deceleration rate of change under the service braking conditions of metro trains in this paper.Experiments were conducted on a metro train using the control parameters before and after optimization.The test results demonstrated a notable improvement in the train's comfort at the three stages,with increases of 15.85%,58.23%,and 58.39%,respectively.
