摘　　要：随着铁道车辆运行速度的提高和轴重的不断增大,车轮在运行过程中产生的擦伤问题更加突出,不仅给铁路部门带来了巨大经济损失,而且严重影响到车辆运行的安全性和稳定性。鉴于此,通过文献调研、机理分析及典型案例处理等手段,对车轮擦伤缺陷进行深入研究,寻找擦伤伤损原因,并提出防范处理措施。With the increase of railway vehicle speed and axle load increasing,the wheels in the process of running abrasion problem become more prominent,not only brought huge economic losses to the railways,and seriously affect the safety and stability of the vehicle.In this paper,by means of literature research,mechanism analysis and typical case treatment,the wheel abrasion defect is deeply studied,find the cause of the abrasion injury,and put forward the prevention and treatment measures.
