N. Kuka, R. Verardi, C. Ariaudo, "Wheel Wear Evaluation on Regional and High Speed Trains using In-House Wear Prediction Tools and Commercial Mbs", in J. Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 256, 2014. doi:10.4203/ccp.104.256

Keywords: railway dynamics, wheel wear, multi-body system, wear, mission profile, wheel and rail profile.

Summary

The increasing demands of railway operators and infrastructure companies concerning life cycle costs and track friendly vehicles require design optimisation in relation to the vehicle-track interface and track damage. To manage the tradeoff between running at high speed on tangent tracks and to have good running in curves, ALSTOM experts concentrated their efforts in the recent years on the optimization of the vehicle design parameters, including the development of a wheel wear calculation tool (AWARE) and the models and methods of simulating the wear evolution on the wheels in terms of profile shape and flange parameters. This paper presents the wear investigations and analysis by using the multi-body system codes SIMPACK and Vampire/AWARE, completing the analysis with a comparison of the wheel wear prediction obtained using simulations with the field data from indoor and on-track tests. Relevant findings of the study are related in particular to the wear of wheel and rail profiles, friction conditions, the maintenance status of the lubrication device and their impact on the track/vehicle interaction.
