Steel in Translation, 2019
The operational wear of rails is analyzed and the actual wear is determined in measurements within the OAO RZhD network and in the laboratory. The wear resistance of rail steel is investigated as a function of the chemical composition and the microstructure (specifically, the dispersity).

Rail Wear Simulation and Validation
2010 Joint Rail Conference, Volume 1, 2010Transportation Technology Center, Inc. (TTCI), a wholly owned subsidiary of the Association of American Railroads (AAR), has developed an iterative rail wear prediction model in the NUCARS® vehicle/track interaction multibody simulation program through internal research and development efforts and with funding from Network Rail (NR) in the UK. The rail

Wear, 1986
Abstract The interactions between the tribological stress parameters and the measurable wear quantities during rolling with slip are examined with the help of experimental results already published and the results of some new investigations by the authors of this paper. It is from these that the following model for wear behaviour is derived. 1. (

The Effect of Rail Material on Wear Behavior of Wheel and Rail
Advanced Materials Research, 2011This study investigates the effect of rail material on their wear behavior of rail-wheel system by using MMS-2A twin-disc abrasion tester. When one type of wheel matches with different types of steel rail, the worn lose of the steel rail decreases with the increasing hardness, and the abrade wear of wheel increases.

An introduction to rail wear and rail lubrication problems
Wear, 1964Abstract It is anticipated that the future trend in railroad's traffic is towards long, heavily loaded, bulk-materials carrying trains. Experience in the effects of this type of traffic on rail life has been studied closely on the Q.N.S. & L. Rly., over the past 8 years of its ore-haul operations. A survey is made of the types of wear which have been

The Influence of Rail Lubrication on Freight Car Wheel/Rail Wear Rates
Vehicle System Dynamics, 1985SUMMARY The effect of wheel and/or rail lubrication in reducing wheel/rail wear rates is evaluated by steady-state curving calculations of a freight car model with conventional and radial trucks. Numerical results indicate that for curves with radii less than 400m, rail lubrication is necesary and the wheel/rail wear rates may be reduced to 1/2.5 of ...

The competitive role of wear and RCF in a rail steel
Engineering Fracture Mechanics, 2005Abstract A model for assessing wear and rolling contact fatigue (RCF) in rails is proposed, with particular emphasis for their competitive role. RCF was studied taking into account different mechanisms of crack nucleation and propagation in different working conditions, and failure indexes are proposed to predict which damage mechanism prevails ...

Detailed metallurgical investigations of worn rails and test discs show that rolling contact fatigue (RCF) crack initiation and early propagation are strongly influenced by microstructure. Also, normally benign, ductile inclusions near and at the rail surface can weaken the microstructure when transversely strain-flattened. The effect of different rail

ANALYTICAL METHODS FOR WHEEL AND RAIL WEAR PREDICTION
Vehicle System Dynamics, 1985SUMMARY The wear algorithm described In this paper has the capability to predict the shapes into which rail vehicle wheels and rails wear in tangent track use. Results of the algorithm applied to a freight car model show that the wheel profiles wear into shapes that are nearly identical for four different wear model formulations examined.

Effects of Rail Hardness on Rail Wear and Head Check Initiation
Transportation Research Record: Journal of the Transportation Research Board, 2016In China, rail head check on heavy-haul railways is the main type of rolling contact fatigue defect, especially since the advent of rail with good wear resistance and high hardness. The influence of hardness on rail wear and head check was explored by use of a method to predict rail head check initiation by considering wear.
