摘要:
鉴于地铁车轮非圆化磨耗导致车轮镟修周期大幅缩短的现状，选取国内某地铁线路，基于踏面清扫装置开展车轮镟修周期改善效果的试验研究。结果表明，踏面清扫装置可有效解决车辆运行过程中产生的非圆化磨耗现象，并可降低车轮轴箱处50%左右的振动加速度；踏面清扫装置作用下踏面磨耗量、轮缘厚度和轮缘综合值与车辆镟后运行里程呈线性增长关系；采用踏面清扫装置可有效提高车轮镟修周期。
Abstracts:
In view of the situation that wheel out-of-roundness wear causes metro wheel reprofiling cycle to shorten greatly, certain domestic metro line is selected to study the improvement effect of wheel reprofiling cycle based on the tread cleaning device. Results show that the tread cleaning device can effectively solve the out-of-roundness wear phenomenon generated during vehicle operation, lowering the vibration acceleration at vehicle axle box by about 50%. Under the action of tread cleaning device, there is a linear growth relationship between the tread wear, flange thickness, QR value, and vehicle operation mileage after reprofiling. The use of tread cleaning device can effectively improve the wheel reprofiling cycle.
