摘要

轨顶(TOR)润滑油通常用于铁路运营中的摩擦控制。它们旨在降低摩擦、减少噪音和磨损,同时确保牵引力/制动力的充分传递。然而,轮轨界面是一个开放系统,因此条件可能会因天气而突然改变,不同的污染物可能会进入接触面并影响这些润滑剂的性能。因此,本研究考察了湿度和露水对两种商用产品的影响,因为这些情况经常出现在轨道上。研究采用了一种基于蠕变曲线测量方法的方法来评估各种情况下的产品性能。所有测量都是在一个球盘配置的通用摩擦磨损试验机上进行的,试验机上覆盖了一个气候室。结果表明,露水对测试产品的影响很大,因为露水降低了产品的性能参数,并造成附着力低的问题。讨论了水油相互作用和氧化第三体层形成的可能机制。主要研究结果表明,如果在露水条件下使用 TOR 润滑油,可能会导致牵引/制动问题。本研究可能有助于今后优化摩擦管理方法。

Assessing the Performance of TOR Lubricants in Humid Environments and Under Dew Conditions

Assessing the Performance of TOR Lubricants in Humid Environments and Under Dew Conditions

Top-of-rail (TOR) lubricants are commonly used for friction control in railway operations. They aim to lower friction and reduce noise and wear while ensuring sufficient transmission of traction/braking forces. However, the wheel–rail interface is an open system, so the conditions may suddenly change due to the weather, and different contaminants may enter the contact and influence the performance of these lubricants. Thus, this study examined the effect of humidity and dew on two commercial products, as these conditions often occur on the track. A methodology based on a creep curves measurement approach was used to assess product performance under various scenarios. All measurements were conducted on a universal tribometer in the ball-on-disc configuration covered with a climate chamber. The results show a strong influence of dew on the tested products, as dew lowered their performance parameters and caused low adhesion problems. Possible mechanisms of water–oil interaction and formation of oxidic third body layers were discussed. The main findings indicate that TOR lubricants may cause traction/braking problems if used in dew conditions. The present study may be helpful in optimising friction management methods in the future.
