自然环境条件下轮轨接触黏着特性研究进展

轮轨黏着是铁路运输中的关键基础性科学问题之一，而轮轨接触界面良好的黏着状态是列车安全和高品质运行的根本保障. 轮轨系统作为1个开放的系统，受到各种自然环境因素的影响，如湿度、温度、水、风沙甚至铁氧化物，而所有的这些环境因素都会影响轮轨接触界面的黏着状态和损伤行为. 本文中综述了水、湿度、温度和风沙等自然环境因素对轮轨黏着特性影响规律的研究进展，分析了自然环境因素下轮轨界面铁氧化物特征，重点探讨了自然环境因素对铁氧化物形成的影响及其对轮轨接触黏着特性的影响规律和作用机理，并提出了轮轨黏着的未来研究方向.Wheel-rail adhesion is one of the key fundamental scientific issues in railway transportation, and a favorable adhesion state at the wheel-rail contact interface is the fundamental guarantee for safe and high-quality operation of trains. As an open system, the wheel-rail system is affected by various natural environmental factors such as humidity, temperature, water, sand and dust, and even iron oxides, all of which can alter the adhesion state and damage behavior of the wheel-rail contact interface. This paper reviews the research progress on the influence laws of natural environmental factors including water, humidity, temperature and sand and dust on wheel-rail adhesion characteristics, analyzes the characteristics of iron oxides at the wheel-rail interface under natural environmental conditions, focuses on exploring the impacts of natural environmental factors on the formation of iron oxides, as well as their influence laws and action mechanisms on the adhesion characteristics of wheel-rail contact, and proposes future research directions for wheel-rail adhesion.
