摘要
随着运量和轴重的不断增加,钢轨伤损情况明显加重。钢轨打磨可以有效解决钢轨的疲劳伤损。为此针对大秦铁路钢轨滚动接触疲劳伤损进行了钢轨打磨方面的研究,简述了大秦铁路钢轨打磨现状,提出了钢轨打磨试验方案。
Along with the continuous increase of the carrying capacity and axle weight, the rail failure is more and more serious. The rail grinding can solve the fatigue damage of the rail effectively. Therefore, this paper makes the research on the rail grinding in the light of the fatigue damage because of the rolling contact of the rail of Daqin Railway, expounds the present situation of the rail grinding of Daqin Railway, and puts forward a set of testing programs of the rail grinding.
