An investigation into the influence of wheel–rail contact relationships on the carbody hunting stability of an electric locomotive

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2022
Carbody hunting stability has attracted more and more attention due to its great influence on the dynamic performance of a railway vehicle. To fully understand the correlation between the wheel–rail contact relationship and the carbody hunting stability of an electric locomotive, the wheel–rail contact geometry analysis and the multi-body dynamics ...

Effect of Wheel-Rail Contact Geometry Relationship on Vehicle Dynamic Performance

Advanced Materials Research, 2013
With the rapid development of high-speed railways, wheel and rail wear has become increasingly serious due to the acute wheel-rail interaction. During the operation of high speed vehicle, complicated wheel-rail contact force will lead to wheel profile wear, which will worsen the dynamic performance of vehicle system, or even influence the safe ...

Influence of the wheel diameter difference on the wheel/rail dynamic contact relationship of the heavy haul locomotive

Australian Journal of Mechanical Engineering, 2018
AbstractRailway vehicles will inevitably appear wheel diameter difference, which will result in an unsymmetrical contact of wheel and rail. Take the guide wheelset for example, analysed the influence of the wheel diameter difference on the wheelset loading state and movement patterns in detail.

Heavy Axle Load Wheel-Rail Contact Stresses and Their Tread-Crown Curvature Relationships

Journal of Engineering for Industry, 1989
This paper presents a theoretical/design analysis of wheel-rail contact stresses and geometries for U.S. freight cars of 70, 95, 100, and 125 ton freight capacities operating on various crown rails. After discussing various types of rail stresses, it is pointed out that the contact stresses are the major factor and the only parameter that enables a ...
