曲线钢轨波磨打磨方法

Grinding Method for Rail Corrugation in Curved Track

摘要:

在研究地铁波磨成因机理基础上，调研分析了现有打磨手段特点和局限性，提出了一种新型的简易打磨方法，实现了更精准和有效的快速打磨.研制了自动化便携式多轮组打磨装置，在地铁线路上进行了打磨试验，并对地铁线路曲线钢轨波磨区段进行了添乘车厢振动和噪声测试以及波磨数据的精确测量.打磨前后的测试数据和波磨测量数据表明，打磨后的线路车辆车厢振动明显降低，打磨前出现的啸叫声完全消失，噪声明显减弱，表明所研制的打磨机对曲线段的钢轨波磨能进行有效治理，打磨效果和效率优于传统的打磨方法和装置.

Abstract:

Based on the study of mechanism of formation of rail corrugation on curved track and investigation of current grinding methods of corrugation, an innovative grinding method was proposed together with a prototype grinding machine with more accurate and efficiency grinding operation. Test grindings on metro line were conducted together with measurements of vibration and noise. The results show that the predicted improvements are obtained with less vibration, lower noise and elimination of screaming noise. The new grinding method is better than the traditional method in convenience and efficiency.
