摘要

车轮和轨道作为支撑和导向系统的功能取决于1.2 × 10−4 m2 (0.2 in2)面积的赫兹接触。除了支撑功能外，该区域还必须承受切向力，以实现牵引、制动和导向功能。这种牵引力伴随着一种被称为“蠕变”的挠度，这种量的经典估计与轨道上的测量结果相比较。描述了轮轨的磨损模式，并讨论了避免接触的替代系统。

The tribology of wheel on rail

The functioning of wheels and rails as a supporting and guiding system depends on a Hertzian contact of 1.2 × 10⁻⁴ m² (0.2 in²) area. In addition to its supporting function, this area must withstand tangential forces to enable the functions of traction, braking and guidance to be fulfilled. Such traction forces are accompanied by a deflection known as ‘creep’ and classical estimates of this quantity are compared with measurements made on the track. Modes of wear of wheel and rail are described and alternative systems which avoid contact are discussed.
