Computational modelling and experimental characterisation of heterogeneous materials [PDF]

open access: yes, 2009
Heterogeneous materials can exhibit behaviour under load that cannot be described by classical continuum elasticity. Beams in bending can show a relative stiffening as the beam depth tends to zero, a size effect.

Impact of wheel shape on the vertical damage of cast crossing panels in turnouts [PDF]

open access: yes, 2015
Impact forces generated in the load transfer area of railway crossing panels lead to a range of degradation modes from wear and fatigue of the contacting materials, fatigue of supporting components to ballast/subgrade deterioration.

Wheel–rail contact: experimental study of the creep forces–creepage relationships [PDF]

open access: yes, 2014
The wheel–rail contact problem plays an important role in the simulation methods used to solve railway dynamics problems. As a consequence, many different mathematical models have been developed to calculate wheel–rail contact forces.

Contact Force Estimation in the Railway Vehicle Wheel-Rail Interface [PDF]

open access: yes, 2011
Increased patronage of railways in the UK in the past 20 years has put demands on rolling stock to operate at peak availability with reduced time available for maintenance.

A practical approach to switching-loss reduction in a large-capacity static VAr compensator based on voltage-source inverters [PDF]

open access: yes, 2000
This paper presents a simple method for reduction of switching and snubbing losses in a large-capacity static VAr compensator (SVC) consisting of multiple three-phase voltage-source square-wave inverters.

Monoposto racecar wheel aerodynamics: investigation of near-wake structure and support-sting interference

open access: yes, 2007
Monoposto racecar development is routinely carried out using wheels supported not by the car suspension but by individual, externally-mounted stings. The interference effect of these stings was acknowledged but unquantified in the existing literature ...

Modelling the Dynamic Behaviour of the Wheel-Rail Interface by Using a Novel 3D Wheel-Rail Contact Model [PDF]

open access: yes, 2011
Methods for multibody modelling and simulation should accurately replicate the dynamic behaviour of rail-wheel interface including precise values for wheel-rail contact positions. This paper studies the development of a novel 3-D wheel-rail contact model

On the near wake of a Formula One front wheel [PDF]

open access: yes, 2013
Velocity measurements were made in the near wake of the front wheel of a Formula One car using a laser Doppler anemometer. Tests were carried out on a 50% scale in a closed-return three-quarter open-jet wind tunnel. Three configurations were investigated
