Prediction of Wheel/Rail Profile Wear

Vehicle System Dynamics, 1997
SUMMARY The alteration in wheel and rail profiles due to wear involves considerable vehicle and track-maintenance costs, and influences the loading capacity of the rails, as well as the operation safety and riding comfort of the vehicles. In the past twenty years a vehicle dynamics, contact mechanics and tribology based research work has emerged which ...

Rail Profile Wear on Curve and its Effect on Wheel-Rail Contact Geometry

Advanced Materials Research, 2013
The paper has carried out continued tests on a curve of a heavy haul railway in China for its rail profiles. Based on the data, the paper has counted the development of the rail profile wear, and then analyses the influence of wheel-rail contact geometry on the rail profile wear.

Effect of Armature and Rails Resistivity Profile on Rail’s Electromagnetic Force and Armature Velocity

IEEE Transactions on Plasma Science, 2015
The electromagnetic force on rails is one of the most important factors that restrict the improvement of railgun performance by deforming, damaging, and reducing its life span. This force is generated by the current flowing through the rail and a magnetic field that is established in the space between the rails that acts as an outward mutually ...

Investigation of initial rail profiles for simplified rail corrugation growth prediction model

Rail corrugation is characterised by bumpy railway tracks, causing undesirable noise and vibrations when trains pass over. The University of Queensland has developed a simplified numerical computer simulation model to analyse the problem in an attempt to identify the most critical parameters that affect the growth of the corrugations.
