The influence of surface roughness in a rail/wheel contact has been a concern for railway
owners since the introduction of 'rail grinding'as a maintenance strategy. Presently, there are …

Rail grinding has been used since the 1980s in maintaining optimal rail profile as well as for
elimination of surface defects such as corrugations and head-checks. Likewise, the wheel …

The objective of this study was to investigate the influence of the surface topography on the
tribological behavior of the wheel/rail contact. Four different groove orientations forming the …

Noise from the wheel–rail interface is a troublesome side effect when railway vehicles
negotiate rail curves. In this laboratory study, two pin-on-disc tribometers were used to …

A stretch of straight rail on the Jing-Hu railway in China has been suffering from
unacceptable levels of side wear. This phenomenon has not previously been investigated …

While many railway engineers are exploring the benefits of the latest lubrication
technologies, bogie types and metallurgies, the wheel/rail (w/r) contact mechanics are often …

Wheel-rail contact is a crucial component in the successful operation of railways. Effective
management of the contact is therefore a very important aspect of rail infrastructure …

A series of experiments on the wheel/rail traction coefficient were carried out with a twin disc
rolling contact machine by varying the surface roughness and the temperature of the wheel …

Rail surfaces exhibit a certain surface roughness from production to millions of overrollings.
This surface roughness cannot be neglected when the mechanisms of sliding–rolling wear …

The objective of this study was to investigate the influence of contaminants on the
tribological behavior of wheel–rail contact. Sand, phosphate, sulfur, and cement were the …
