摘要
介绍广州地铁采用的2种钢轨打磨方法,重点论述“预防性打磨”方法的原理、应用和优缺点,指出预防性打磨能有效地控制钢轨侧磨、疲劳和波磨,改善轮轨接触状况,降低轮轨噪声,延长钢轨使用寿命。
Two types of rail grinding techniques adopted in Guangzhou metro are introduced in the paper. The principle, the application as well as the virtues and defects of the preventive grinding approach are highlighted. It is shown that the preventive grinding can effectively control the side wear, fatigue and corrugation, improve the interaction between the wheel and rail, suppress the wheel - rail noise as well as prolong the life of the rail.
