摘　　要：在城市轨道交通节能方面,列车牵引能耗占有较大比重。为了在运能优化及节能之间找到平衡点,需对灵活编组列车牵引能耗进行分析,作为协调便捷性及经济性的参考依据。根据经典力学建立列车牵引能耗数学模型,为方便研究又建立了牵引能耗理想模型,通过分析杭州地铁某线路线历史运营数据,对其关键参数进行拟合研究,对拟合好的关键参数的关系式曲线进行鲁棒性验证。基于杭州地铁某线路的实际数据对建立的牵引能耗理想模型进行仿真验证,拟合结果为牵引能耗理想模型提供数据支持,并为牵引能耗理想模型的去理想化奠定基础,可在实际项目中推广应用,具有较好的理论价值和实际意义。In terms of energy saving of urban rail transit,traction energy consumption of trains occupies a large proportion.In order to find a balance between transport capacity optimization and energy saving,traction energy consumption of trains with flexible grouping should be analyzed as a reference for convenience and economy of coordination.A mathematical model of train traction energy consumption is established according to classical mechanics,and an ideal model of traction energy consumption is established for the convenience of research.By analyzing the historical operation data of a Hangzhou Metro line,the key parameters are fitted and the robustness of the relationship curve of fitted key parameters is verified.Based on the actual data of a Hangzhou metro line,the ideal model of traction energy consumption is simulated and verified.The fitting results provide data support for the ideal model of traction energy consumption,and lay a foundation for the deidealization of the ideal model of traction energy consumption.It can be popularized and applied in practical projects,and has good theoretical value and practical significance.
