针对我国动车组关键引进部件轮对的疲劳强度试验还未形成完整规范的现状,归纳总结德国、意大利、日本、中国轮对疲劳强度试验情况,分析各自的优点及不同之处。在此基础上,为我国轮对疲劳强度试验台的建设,以及制定高速客车、动车组轮对疲劳强度试验标准提供参考。 In view of the fact that the fatigue strength test of the wheelsets of the key imported components of EMU has not yet formed a complete standard, this paper summarizes the fatigue strength tests of wheelsets in Germany, Italy, Japan and China and analyzes their respective advantages and differences. On this basis, it provides a reference for the construction of fatigue strength test-bed in our country and the formulation of test standards for fatigue strength of high-speed passenger cars and EMUs.
