摘　　要：高铁车轴是高速铁路列车的关键技术之一,是关系到列车运行安全性、可靠性的重要结构,世界各主要铁路发达国家都已形成了比较系统的车轴强度设计方法和规范。文章对比分析了欧洲和日本的相关标准在高铁车轴设计原理上存在的差异,介绍了国内外车轴疲劳试验装置和试验方法,给出了改善疲劳性能的主要对策及建议。The axle for high speed railway is one of the key technologies for high speed railway trains and an important structure related to safety and reliability of train operation.The fairly systematical axle strength design method and regulations have been formed in main advanced countries in railway in the world.In this paper,differences existing in the design principles for high speed railway axles in relevant standards in Europe and Japan are compared and analyzed.The fatigue test device and test method for axles in China and abroad are described.The main counter measures and suggestions are given to improve the fatigue performance.
