摘要:
［目的］由于城市轨道交通(以下简称“城轨”)车辆新增的全自动驾驶技术、高冗余性技术等均在不同程度上增加了车载设备的数量，导致城轨车辆的质量越来越大,且由于城轨车辆的总体运量较大，导致其总体耗电量也维持在一个较高的水平。因此，需对城轨车辆的减重节能技术进行研究。［方法］分别介绍了车体、牵引系统及辅助电源系统、转向架及制动系统、空调系统及车门系统、车钩及贯通道、车辆内装及客室设备的减重措施；分别介绍了牵引系统及辅助电源系统、空调系统和照明系统的节能措施。［结果及结论］可采用的减重措施主要有：车体采用全铝结构；牵引系统采用永磁同步电动机；辅助电源系统采用高频辅助逆变器；充电机采用高频软开关设计；转向架采用轻量化设计；制动系统采用模块化设计；内装及客室设备采用新型材料。可采用的节能措施主要有：牵引系统采用永磁同步电动机；辅助电源系统采用高频拓扑结构；空调系统采用变频技术；照明系统采用OLED(有机发光二极管)光源。应用所介绍的减重及节能措施，基本能够达到车辆整体减重10%以上、节能10%以上的目标。
Abstracts:
［Objective］ The increasing use of fully automated driving and high-redundancy technologies in urban rail transit vehicles (hereinafter referred to as ′metro′) leads to the increase of on-board device amount to varying degrees, resulting in the increasing mass of metro vehicles. Additionally, due to the significant overall transport capacity of metro vehicles, their overall energy consumption remains at a higher level. Therefore, it is necessary to study the light-weighting and energy-saving technologies for metro vehicles. ［Method］ Measures for reducing the weight of carbody, traction and auxiliary power systems, bogies and braking systems, air-conditioning and door systems, couplers and gangways, as well as vehicle interior and compartment equipment, are introduced. Energy-saving measures for the traction and auxiliary power systems, air-conditioning system, and lighting system are presented respectively. ［Result & Conclusion］ Feasible light-weighting measures include adopting a full aluminum carbody structure for , utilizing permanent magnet synchronous motors for the traction system, employing high-frequency auxiliary inverters for auxiliary power system, implementing high-frequency soft-switching design for chargers, adopting light-weighting design for bogies, modular design for braking system, and new material for interior and compartment equipment. Available energy-saving measures include the adoption of permanent magnet synchronous motor in traction system, the application of high-frequency topological structure for auxiliary power system, the use of frequency converter technology for air-conditioning system, and OLED (organic light-emitting diode) light sources for lighting system. By implementing the described light-weighting and energy-saving measures, the target of vehicle overall light-weighting by over 10% and achieving energy-saving of over 10% can be effectively realized.
