摘　　要：钢轨钢的接触疲劳一直为铁路运输部门和研究机构所重视。轮 -轨经过长时间滚动接触会导致轨面剥落 ,产生疲劳。本文综述了钢轨钢的滚动接触疲劳特征及其成因 。The surface spalling and fatigue failure may occur after a long time of service during wheel rail rolling contact. The characteristics of wheel rail rolling contact fatigue and causes of induced fatigue were reviewed. Some practical countermeasures to improve fatigue resistance for rail were suggested.

关 键 词：钢轨钢 滚动接触疲劳 疲劳寿命
