Wear Prediction of Curved Switch Rail in High-Speed Turnout and Influence of Wheel and Rail Wear on Vehicle Dynamic Performance

Analysis of wheel and rail Hertzian and Non-Hertzian contact theories using UM software considering the effect of rail inclination on wheel wear

Wheel-rail interaction has always been one of the issues in the railway industry. In this paper, the effect of Hertzian and non-Hertzian contact theories on the wheel wear due to the rail inclination was investigated. by using the UM software. According to the results, longer contact areas are obtained in non- Hertzian contact theory compared to Hertzian contact theory. In non-Hertzian contact...

A Study of the Wear Behavior of a Rail Material

The rail track is one of the most important elements of a railway system. During the passage of trains, the rails are subjected to contact load that comes from the wheels of the train.  The railway track often fails in service due to wear caused by contact fatigue and other wear damage mechanisms that could also limit the life span of the railway infrastructure and railway vehicle. The aim of t...

Dynamic Analysis of High Speed Rail-Vehicle Collisions

In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...
