Abstract Transient adhesion effects in rolling–sliding contacts influence all aspects of train–track interaction. This is of high importance specifically when these effects result in critically low adhesion, which poses a risk to traction and bra

Wheel maintenance is a complex process whose costs can be reduced with good planning. One of the main difficulties is the prediction of a worn wheel profile shape on a train. With existing modelling approaches, it is possible to predict a worn wheel

This paper presents a new approach for modelling the wear in wheel-rail contacts for a wide range of test and contact conditions (material pairing, load, creep, lubrication etc.) in the mild and severe wear regimes with one set of model coefficients.

Train operators report low adhesion in autumn, which they suspect is caused by fallen leaves on a track surrounded by forest and farmland. To investigate and quantify this effect, vehicle tests have been performed in autumn on a track partially surro

Self-excited torsional wheel-set axle vibrations can lead to polygonization of wheels, cause discomfort for the passengers, and can lead to issues with the stability of the press-fit between wheel and wheel-set. To predict their amplitude, three diff

A computationally efficient engineering model to predict adhesion in rolling contact in the presence of water is presented which may be implemented in multibody dynamics software or in braking models to study train performance and braking strategies.

Simulating the wheel/rail contact of a train is traditionally conducted using small-scale twin-disc testing. Here an emerging alternative method, the “high pressure torsion” (HPT) test is introduced. This has advantages over twin-disc testing as

Friction within the wheel–rail contact highly influences all aspects of vehicle–track interaction. Models describing this frictional behaviour are of high relevance, for example, for reliable predictions on drive train dynamics. It has been shown
