摘　　要：文章通过对某正在运营既有地铁车辆和转向架的研究,探讨其能否将最高运营速度从80 km/h提高到120 km/h。同时,详细分析转向架中驱动装置、基础制动装置和悬挂装置等结构及设计计算过程,并提出提速改造的技术可行性分析和改造方案,为后续详细技术方案实施提供参考。This paper discusses whether the maximum operating speed can be increased from 80km/h to 120km/h on the operating metro vehicles and bogies.The vehicle structure and design course of the traction devices in bogies,the foundation brake rigging,the suspension device,and the vehicle gauge are analyzed in detail.Therefore,the technical feasibility and ideas of the speed increase reform are put forward as a reference for the implementation of the subsequent technical solutions.
