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 ...

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 ...

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.

Optimal design of rail grinding patterns based on a rail grinding target profile
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2016Based on the grinding target profile of the rail and the grinding capacity of a single grinding stone, a numerical calculation method for rail grinding patterns that includes grinding angle and grinding power of each grinding stone of the GMC96 rail grinding train was designed and established.

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.

Prediction of Wheel/Rail Profile Wear
Vehicle System Dynamics, 1997SUMMARY The alteration in wheel and rail profiles due to wear involves considerable vehicle and track-maintenance costs, and influences the loading capacity of the rails, as well as the operation safety and riding comfort of the vehicles. In the past twenty years a vehicle dynamics, contact mechanics and tribology based research work has emerged which ...

Rail Profile Wear on Curve and its Effect on Wheel-Rail Contact Geometry
Advanced Materials Research, 2013The paper has carried out continued tests on a curve of a heavy haul railway in China for its rail profiles. Based on the data, the paper has counted the development of the rail profile wear, and then analyses the influence of wheel-rail contact geometry on the rail profile wear.

The electromagnetic force on rails is one of the most important factors that restrict the improvement of railgun performance by deforming, damaging, and reducing its life span. This force is generated by the current flowing through the rail and a magnetic field that is established in the space between the rails that acts as an outward mutually ...
