“复兴号”17辆编组动车组列车总线网段扩展的设计研究

Train bus network segment expansion design of 17 car marshalling EMU of “Fuxing”

摘要: 近年来，我国高速铁路营业里程与铁路运力持续上涨。为应对铁路列车复杂度与综合性的巨大变化，对动车组进行多功能车辆总线（MVB，Multifunction Vehicle Bus）、绞线式列车总线（WTB，Wire Train Bus）网段的改进，通过分析测试数据，验证了传统动车组扩展MVB及WTB网段的可行性。网段的扩展，可提高传统动车组的运力，显著提高客运列车的利用率。

Abstract: In recent years, China's high-speed railway business mileage and railway capacity continue to rise. In order to cope with the great changes in the complexity and comprehensiveness of railway trains, this paper improved the network segments of Multifunction Vehicle Bus(MVB) and WTB(Wire Train Bus) for EMU. Through the analysis of test data, it was verified the feasibility of traditional EMU expanding MVB network segment and WTB network segment. The expansion of network segment can improve the transport capacity of traditional EMUs and significantly improve the utilization rate of EMU.
