| 摘 要： | 研究了南京地铁列车车轮踏面非正常沟状磨耗的成因.对车轮、钢轨的外形、材质和硬度等进行了测试,分析了轮轨接触和制动磨损的影响,提出了沟状磨耗的原因.测试结果分析表明,该地铁车辆拖车轮踏面上的凹槽磨耗主要是由于在制动施加频度过高、轮轨接触又不均匀的内因作用下产生的.

| Abstract: | An investigation is carried out for a severe groove wear on the wheel treads of Nanjing metro vehicle, then a measurement of wheel/rail profiles and an analysis of material components and a test of the hardness of surface materials are taken. The results show that the groove wear are mainly caused by wheel/rail contact and the effect of highly frequent brake on the wheel tread. |
