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.

Study on automatic alignment algorithm in rail grinding of rail head profile
2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2017Rail profile alignment algorithm determines the amount of rail-grinding, the distribution of grinding heads, and directly affects the final grinding effect. The alignment algorithm based on the rail waist profile has been proposed. The paper studied the high accurate and automatic alignment algorithm based on the rail head profile.

Rail Profile Condition Monitoring Information Analysis of UK Rail Track
2009 International Conference on Computing, Engineering and Information, 2009Condition based monitoring system can be used to determine how and why there were defects in rail profile. Such system helps in identifying trends for effective and efficient condition monitoring of rail profile. One such way is an in depth by information analysis of rail profile parameters by correlation analysis thus finding significant correlations ...

Influence of Wheel-Rail Profiles on the Hunting Vibrations of Rail Vehicle Trucks
Journal of Vibration and Acoustics, 1985The effect of several wheel and rail profiles on the hunting behavior of three-piece North American freight truck is investigated by the method of describing functions. After replacing the nonlinear terms by their equivalent describing functions, the differential equations of motion are converted to a set of coupled nonlinear algebraic equations which ...

Determination of Rail Vertical Profile through Inertial Methods
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2010Undergrounds and other metropolitan railway systems are characterized by their intense traffic, lasting up to 20 h per day, and so they need their maintenance work programmes to be optimized, implying an optimization of the monitoring processes. This article proposes an alternative to the traditional optical methods for monitoring rail profiles which ...

Regarding the issue of rail profile constructing
Ferrous Metallurgy. Bulletin of Scientific , Technical and Economic Informationhe operational durability of railway rails, along with steel purity, physical and mechanical properties, and straightness, depends on the rail profile: the dimensions of its elements and the weight per linear meter. To date, the only rail profiles used on mainline railways in Russia are the P50, P65, and P75, which were developed in the middle of ...

Structural and Multidisciplinary Optimization, 2020
The LM wheel profile and profile of Chinese 60 kg/m rail (LM&CHN60) are commonly used in the Chinese metro. However, the poor matching between wheel and rail profiles as well as the instability of the vehicle often occur on some curved sections due to wear.

A design method for rail profiles based on the geometric characteristics of wheel–rail contact
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2017Designing a proper rail profile carries more significance than designing a wheel profile because of the amount of work and cost involved in the maintenance of rails. A better rail profile will not only help to ensure achieving the desired dynamic performance of rail vehicles but it also extends the service life of rails.
