摘要
针对快慢车组合的市域快线节能坡优化开展研究。首先提出市域轨道节能坡优化的总体框架,开展列车节能运行操纵策略实验和标准三站两区间的节能坡数值实验,得到设计规律。在此基础上,结合广州地铁18号线实际工程数据,对全线节能坡方案进行优化探讨。结果表明,快慢车组合运营线路的节能坡设计主要受快慢车比例和快车跨站限速影响,当快车比例较大、跨站限速高时采用小站缓坡更加节能。方案理论上节能效果显著,证明了方法的有效性。
This study discusses the design of line vertical alignment for multiple trains.We first put forward the overall design framework of the regional express rail vertical alignment,and then carry out numerical experiment to choose energy efficient train control strategy.The experiment shows the relationship between the gradient value and train traction energy consumption.On this basis,the method is applied to a real world practical engineering of Guangzhou Metro Line for test.The results show that the energy efficient vertical alignment design is affected by the proportion of sprinter to express trains as well as the through speed limit.The design proves the effectiveness of the method.
