Influence of Wheel Wear Depth on Wheel-rail Dynamic Performance in Fast Metro Line Turnout Zone
Chengshi guidao jiaotong yanjiuObjectiveOn fast metro lines with speeds of 120 km/h and above, wheel wear develops quite rapidly, and intense wheel-rail interactions occur when trains pass through turnouts, necessitating an investigation into the influence laws of wheel wear depth on ...

Wheel/Rail Contact Geometry of Different Wheel Tread Profile in High-Speed Railway Turnout
, 2011 Train/turnout dynamic interaction is exacerbated by high speed of passenger train and heavy load of freight train, and wheel/rail relation is one of the key factors that determine the running characteristics of the train. Focusing on three types of wheel

In this paper the dynamic behaviour of several unconventional bogies is compared. The study takes into account the radius of the curve and the maximum level of wear allowed to the wheels. Ranges of conicities and curve radius in which each bogie is advantageous are studied, for both high-speed and urban transit vehicles.
