The Wear of Grinding Wheels: Part 2—Fracture Wear

Journal of Engineering for Industry, 1971
The nature and extent of grinding wheel wear in precision grinding were investigated directly from the wear particles removed from the wheel. A statistical analysis of the wear particle size distributions was developed to determine the relative amounts of bond fracture, grain fracture, and attritious wear.

More Wheels, Less Wear

Industrial Lubrication and Tribology, 1993
Current weight restrictions mean that new‐design, 44‐tonne road tankers are having to operate at less than full capacity, even though the trailers are no longer, and the vehicles cause no more road wear than existing 38‐tonne tankers.

Influence of the dressing process on grinding wheel wear

Production Engineering, 2015
The generation of the grinding wheel topography is described in many different models and approaches. These models do not consider the influence of the dressing process on the wear of the grinding wheel. In particular the prediction of this wear dependent on the dressing process parameters is not possible with the currently available models.

Numerical Simulation of Wear in Railway Wheel Profiles

Volume 3: Dynamic Systems and Controls, Symposium on Design and Analysis of Advanced Structures, and Tribology, 2006
The work describes a method to predict the evolution of the wheel profile of a railway vehicle, depending on the load history acting on the wheelset. The method is based on the determination of the wear on the contact area, which is divided into finite elements according to the strip theory. For each element, in presence of slip, the amount of material

ANALYTICAL METHODS FOR WHEEL AND RAIL WEAR PREDICTION

Vehicle System Dynamics, 1985
SUMMARY 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 wheel–rail contact modelling on wheel wear simulation

Wear, 2016
Abstract Three non-elliptic contact models, namely Kik–Piotrowski method, STRIPES and ANALYN, are first compared to the Hertz theory and the CONTACT code in terms of the normal contact solution. Further, for the contact models except for CONTACT, the tangential contact solutions are calculated by a modified simplified theory of Kalker (FASTSIM) based

Wheel wear in dry surface grinding

International Journal of Machine Tool Design and Research, 1976
Abstract Wear phenomena accompanying dry surface grinding of mild steel under plunge cut conditions were investigated from the force pattern, grinding ratio and wear particle size removed from the wheel. Wheel wear estimates were obtained from the amount of abrasive grains collected during grinding.

Wear of High-Speed Railway Wheels

1969
An introduction of the presently running wheels on the New Tokaido Line and the results of fundamental researches carried out beforehand in order to determine their configuration and material treatment are presented herein. A general description of a high-speed wear-testing machine is stated in the beginning, followed by the results of fundamental ...

Wear modelling in rail–wheel contact

Wear, 2015
Abstract In rail–wheel transports the maintenance interval for both wheels and rails has become a major issue in reducing costs and increasing safety and has encouraged the development of new numeric procedures for predicting the evolution of wear in order to establish a convenient maintenance schedule.
