摘　　要：采用大量新装备的高速动车组近年来在我国获得广泛应用,是铁路客运最为有效的运输工具之一。动车组车轴是动车组走行部中非常重要的部件,承受着源自车体及轨道的各种载荷,其中主要是旋转弯曲载荷和扭转载荷。动车组车轴要保证在所规定的使用条件下,具有足够的安全性、可靠性和长使用寿命,这就对车轴材料相关技术提出了非常高的要求。目前我国各型动车组车轴尚未完全实现国产化,标准也是采用国外的相关标准。本文在仔细对比研究国外成熟的动车组车轴标准基础上,探讨了车轴材质、性能的现状,此外,还对动车组车轴材料相关技术进行了展望。High-speed EMU equipped with a large number of new components is widely used in recent years in our country,and it is one of the most effective conveyances for passengers.EMU axle is a very important part,which suffers from variety loads of body and track,mainly rotating bending and torsion loads.Ensuring the EMU axle with sufficient security,reliability and long service life proposes very high demands for the axle material technologies.Currently various types of EMU axle have not yet achieved localization,and the standard also uses abroad standards.Based on the careful comparison of EMU axle foreign mature standards,this paper discusses the current situation of axle material properties,and also forecasts the technical development of EMU axle.
