Wheel–rail contact: experimental study of the creep forces–creepage relationships [PDF]
Vehicle System Dynamics, 2014 [EN] The wheel rail contact problem plays an important role in the simulation methods used to solve railway dynamics problems. As a consequence, many different mathematical models have been developed to calculate wheel rail contact forces.However, most of them tackle this problem purely from a theoretical point of view and need to be experimentally ...

The effect of track alignment irregularity on wheel-rail contact geometry relationship in a turnout zone [PDF]
Journal of Modern Transportation, 2012 The irregularity is a key factor affecting the wheel-rail contact geometry relationship. In this paper, we calculated the wheel-rail contact points at typical sections and obtained the longitudinal variation of the wheel-rail geometry relationship with the trace line method.

The Effect of Track Irregularities on Wheel-Rail Contact Relationship
, 2016 Track irregularity is an inevitable problem in any rail network and it is the source of track deterioration and degradation. This becomes evident in railway projects spanning cities. Hence, the effect of track irregularities on wheel-rail contact relationship is studied with the aim to solve the contact geometry and contact pressure problems induced by

Design Method of Rail Grinding Profile Based on Wheel Rail Contact Relationship
AbstractWhen the railway track is damaged, it is essential to grind it in in a timely manner to enhance the wheel-rail contact performance. This paper relies primarily on the rolling radius difference function as the main design basis, taking the expected distribution between the wheel and the rail as the boundary condition. In cases where the abscissa
