Modelling of suspension components in a rail vehicle dynamics context

Vehicle System Dynamics, 2011
Suspension components play key roles in the running behaviour of rail vehicles, and therefore, mathematical models of suspension components are essential ingredients of railway vehicle multi-body models.

Hardening of Rail Vehicle Axles

Solid State Phenomena, 2022
The development of the technology for laser hardening of the axle seats of rail vehicles aims to improve the high-cycle service life of these axles under wheel pressing and thus to increase safety in rail transport. Laser hardening can create high compressive stresses that increase the fatigue resistance of the material.

A survey of wheel–rail contact models for rail vehicles

Vehicle System Dynamics, 2016
ABSTRACTAccurate and efficient contact models for wheel–rail interaction are essential for the study of the dynamic behaviour of a railway vehicle. Assessment of the contact forces and moments, as well as contact geometry provide a fundamental foundation for such tasks as design of braking and traction control systems, prediction of wheel and rail wear,

Application of the ACFM inspection method to rail and rail vehicles

Insight - Non-Destructive Testing and Condition Monitoring, 2005
The ACFM inspection technique is an electromagnetic inspection method, which is widely used in the oil and gas industry for the detection and sizing of surface-breaking cracks. It provides a number of advantages over conventional inspection methods, particularly in the ability to inspect without removing coatings or grease, and has recently been ...

Light rail vehicles and running safety

ASME/IEEE Joint Railroad Conference, 2002
The basic standard US LRV structural designs are virtually unchanged from those adopted 25 years ago based on a modified European subway car. With only one exception, these have not been significantly updated for or adapted to the high levels of in-street running found more and more on new light rail systems or for increased passenger safety in general.

Lateral Oscillations of Rail Vehicles

Journal of Fluids Engineering, 1935
Abstract The authors point out in this paper that lateral oscillations, which either do not occur or are negligible at slow train speeds, are of vital importance at the high train speeds now demanded by the railroads in order for them to compete successfully with the swiftly moving automobile and the much swifter airplane.

Study on the crashworthiness of rail vehicles

Proceedings of the 2001 IEEE/ASME Joint Railroad Conference (Cat. No.01CH37235), 2002
Crashworthiness requirements are appearing more frequently in rail vehicle technical specifications. These requirements represent an effort to reduce the number of injuries and fatalities to rail passengers in collisions. There are relatively few published studies which provide methodologies for analyzing the crash behavior of rail vehicles. This paper

Energy efficient control of rail vehicles

2001 IEEE International Conference on Systems, Man and Cybernetics. e-Systems and e-Man for Cybernetics in Cyberspace (Cat.No.01CH37236), 2002
This paper describes an analytical method of computation of optimal controls which minimize the energy consumption by rail or any other fixed path vehicles. A specific aspect of this problem is that the external forces applied to the vehicle and the maximum allowable speed depend on the coordinate of the vehicle.

Digital Twins for Rail Vehicle Designs

This chapter describes the application of digital twin techniques in the design phase of railway vehicles. The design phase can gain important benefits from the application of digital twin techniques that allow the creation of reliable numerical models to predict the behavior of the vehicle during service.

The development of rail vehicle crashworthiness

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2002
The conscious design of passenger vehicles to provide protection to passengers in the event of collision accidents is a development of the second half of the twentieth century. This paper traces the major steps taken along this path in Europe and the United Kingdom and relates the development of the associated structural standards to the emerging ...
