On the study of train-track dynamic interactions caused by rail welds on discrete supported rails
(Elsevier, 2014-06-15)
The paper studies the influence of rail weld dip on wheel-rail contact dynamics, with particular reference to freight trains where it is important to increase the operating speed and also the load transported. This has ...
Wheel-rail wear index prediction considering multiple contact patches
(Elsevier, 2009-06)
This paper shows a new wheel-rail contact model specially suited to obtain wear indexes between wheel and rail when the vehicle negotiates tight curves. The model presented in the paper enables introduction of the two ...
