The Outlier and Integrity Detection of Rail Profile Based on Profile Registration
IEEE Transactions on Intelligent Transportation Systems, 2020For rail wear measurement, the process of profile registration is critical. Nowadays, the widely used method is the rail waist double circle segment method (DCS). However, this method may be invalid in actual applications because of the influence of the following two factors: one is the outliers mixed into profiles and the other is the profile ...

Proceedings of the 1995 IEEE/ASME Joint Railroad Conference, 2002
The subject of determining the proper profile of either the wheel or rail has long been a source of controversy. Practices have evolved and become common in monitoring the rail profile and keeping it in conformance with researched profiles that offer maximum rail life. However, with the wheel, preventative measures to maintain the accepted profile have

3D rail modelling and measurement for rail profile condition assessment
2017 IEEE AFRICON, 2017To ensure safety and reliability, compliance to rail regulations and efficient predictive maintenance, regular condition assessment needs to be carried out on the railway infrastructure. The consequence of not carrying out condition assessment measurement results in poor knowledge of track conditions that should trigger maintenance and rehabilitation ...

On the stiffness hysteresis of profiled rail guides
Tribology International, 2021Abstract Profiled rail guides are standard components extensively used in machine tools. While produced and developed further for decades, this paper shows for the first time nonlinear hysteretic behavior in the deflection response to mechanical loading after preload liftoff.

Predictive Maintenance Management of Rail Profile in UK Rail
2009 International Conference on Computing, Engineering and Information, 2009Preventive Maintenance finds the commencement of failure and helps them in mitigating them. It can also help in uncovering hidden failures.Preventive maintenance management can be used to determine defects in rail profile and prevent them happening in future.

IET International Conference on Railway Condition Monitoring, 2006
The dynamic response of a railway vehicle is dependent upon the interaction between the wheel and rail. Currently these key components are monitored for wear and condition off-line and separately. However, it is the combined nonlinear interaction that really affects the dynamics.

Research on Calibration Method of Rail Profile Measurement System
Journal of Circuits, Systems and Computers, 2023The rail profile measurement system is used to obtain the full section profile of the rail, which is the core of the wheel/ rail interaction, based on the principle of infrared structured light. The system calibration is the key as to whether the accuracy is high enough to guide the railway maintenance.

DESIGN STRATEGY FOR WHEEL AND RAIL PROFILES IN ORDER TO DECREASE THE WEAR OF WHEELS AND RAILS
Vehicle System Dynamics, 1985SUMMARY Relationship between creep force and a slip angle has the same character as between aerodynamic force and an attack angle. The characteristic of creep force is changed according to the contact condition between a wheel and a rail. It is strongly affected by the sectional profile of a wheel and a rail.

The application of contact mechanics to rail profile design and rail grinding
Wear, 2002Abstract While many railway engineers are exploring the benefits of the latest lubrication technologies, bogie types and metallurgies, the wheel/rail (w/r) contact mechanics are often overlooked or poorly controlled. But the geometry of the w/r contact permeates every facet of the w/r interaction, having profound effects on wear, fatigue, corrugation,
