Passengers, seats and carbody in rail vehicle dynamics

open access: yes, 2002
Reliable models of passengers, seats and carbody are essential in order predict ride comfort of rail vehicles. This paper extends previously presented models of passenger-carbody interaction to include vertical seating dynamics.

Rail vehicle noise

open access: yes, 1963
There was a time when noise from rail vehicles - especially subway trains - was always placed at the top of the list of unpleasant noises. In recent years the picture has changed somewhat. On the one hand even more noisome noises such as jet aircraft have become commonplace; and on the other, there has been a substantial effort to reduce rail vehicle ...

Structure design, analysis, and optimization of 12-pole radial magnetic bearing

open access: yesAdvances in Mechanical Engineering
Active magnetic bearings (AMBs) are widely used in high-speed turbines, precision machining, and energy storage systems due to their non-contact operation, high rotational speeds, and low maintenance.

An investigation into inconsistencies between theoretical predictions and microphone array measurements of railway rolling noise [PDF]

open access: yes, 2007
Theoretical models, such as TWINS, and microphone array measurements have been widely used to gain better understanding of rolling noise. However, the array measurements are often inconsistent with the TWINS predictions and give less prominence to the ...

Reduction of Corrugation by Semi-Active Track

open access: yes, 2004
This article discusses possibilities for application of semi-active actuators to reduce rail and wheel wear. A simple model of a vehicle/track interaction is presented. The model is extended with a model of semi-active actuators. The feedback control law

Reducing the Diameter of Freight Vehicle Wheels – The Suitability of Q/D as a Control for Wheel-Rail Contact Stress

open access: yes, 2013
High wheel-rail contact stress is related to rail damage mechanisms such as gross plastic flow. Such high contact stresses are often generated by freight vehicles which have comparatively high axleloads.

The influence of support conditions on short- and long-term track behaviour

open access: yes
Railway track support conditions are known to deeply affect the dynamic performance of vehicle-track interaction, influencing the state of the track system both in the short and in the long term.

Understanding urban rail travel for improved patronage forecasting

open access: yes, 2013
Improved forecasting of urban rail patronage is essential for effective policy development and efficient planning for new rail infrastructure. Past modelling and forecasting of urban rail patronage has been based on legacy modelling approaches and often ...
