摘要:

高速動車組列車近年來在國內外獲得廣泛應用，是鐵路客運最為有效的運輸工具之一。高速列車車軸是動車組走行部中非常重要的部件，承受著源自車體及軌道的各種載荷，其中主要是旋轉彎曲載荷和扭轉載荷。高速列車車軸要保證在所規定的使用條件下，具有足夠的安全性、可靠性和長使用壽命，這就對車軸材料及相關技術提出了非常高的要求。對比研究了國內外高速列車車軸技術，探討國內外高速列車車軸的生產工藝流程、化學成分-組織-性能和結構設計等，在此基礎上，對時速400 km以上的新一代高速列車車軸材料的發展方向進行了展望。目前，我國正基于材料基因組技術研發時速400 km的高速列車車軸用鋼，這在世界上尚無先例。

Abstract:

High speed electric multiple units (EMU) train has been widely used in recent years at home and abroad. It is one of the most effective conveyances for passengers. The axle for high speed train is a very important part, which suffers from various loads of body and track，mainly including rotating bending and torsion loads. Ensuring the EMU axle with sufficient security, reliability and long service life raises very high demands for the axle material technology. Based on careful comparison of EMU axle technology at home and abroad, this paper discusses the process, chemical composition-microstructure-property relation, structure design etc., and forecasts the technological development of new generation axle for EMU with more than 400 km/h speed. At present, the axle steel for EMU with more than 400 km/h speed is being developed based on Materials Genome Initiative(MGI) technology in China.
