中文摘要:
      随着铁路客货运量的增大和列车速度的提高,使得高速铁路的轨道必然比普通线路具有更高的安全性、可靠性和平顺性,为保证轨道结构的这些要求,轨道各部件的力学性能、使用性能和组成为结构的整体性能都比普通轨道部件高,但在高速铁路轨道上仍然存在很多问题。目前,轮轨接触疲劳是最常见的轮轨问题,国内外许多学者对此做了研究。导致机车车辆轮轨接触疲劳的因素有很多,指出了当下一些常见的轮轨接触疲劳损伤形式,同时对滚动接触疲劳的影响因素进行了简要分析。为了研究疲劳损伤产生、发展的机理和影响因素,通过查阅大量资料,了解了各种常见损伤的产生和发展机理,并总结了在该领域的研究方向与热点,同时指出了当下高速铁路建设中存在的技术难题。结合轮轨接触疲劳的失效形式和磨损的特点,从材料对踏面的影响、高速与重载对轮轨接触疲劳的影响、润滑剂对轮轨裂纹增长的影响等方面,进一步提出预防和减缓钢轨接触疲劳损伤的具体措施。
英文摘要:
      With the increase of train speed as well as passenger and freight volume, high-speed rail track is inevitably required to provide higher level of security, reliability and smoothness than ordinary lines. In order to guarantee these requirements of track structure, mechanical properties, usability and overall structural performance of the various track components shall be much higher than that of ordinary track components. However, a lot of problems are still present in the high-speed railway track. Currently, wheel/rail contact fatigue is the most common problem in the wheel-rail issues. Many domestic and foreign scholars have made efforts in study such problem. Locomotive wheel/rail contact fatigue is caused by various factors. Some common existing forms of wheel-rail contact fatigue damage were pointed out in this article. Meanwhile, influence factors of the rolling contact fatigue were briefly analyzed. In order to study the fatigue damage generation&development mechanism and influence factors, generation&development mechanism of various common damages were understood by referring to mass data. In addition, the research directions and focuses in this field were introduced and existing technical problems in current high-speed railway construction were put forward as well. By combining failure mode with wear characteristics, specific measures were further put forward to prevent and reduce steel rail contact fatigue from aspects including impact of materials on tread, impact of high speed and heavy load on the wheel/rail contact fatigue, lubricants on wheel/rail crack growth.
