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

, 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.

Analysis of the Influence of Incorporating Different Thermal-Insulating Materials into the Sub-Ballast Layers

Buildings
Adverse climatic conditions, particularly excessive water and frost, necessitate the design of thick protective sub-ballast layers when dealing with frost-susceptible subgrade surfaces, especially when using standard natural materials (crushed aggregate ...

Control Strategy of the Brake Dynamics for Railway Vehicles Equipped with Anti-Slip-Device [PDF]

, 2006
From the point of view of railway vehicle braking processes it is an important requirement to maintain the roll-ing-motion-state of the wheels, i.e. the macro-sliding-free rolling contact between the vehicle wheels and the rail-head, since in the course ...

Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

Journal of Animal Ecology, EarlyView.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.

ROLLING NOISE SIMULATION OF A RAILWAY VEHICLE [PDF]

, 2013
Rolling noise of the railway vehicles is occurred by the wheel/rail vibration excited bythe rolling surfaces roughness. This paper presents an acoustic model able to predict the rollingnoise level of a railway vehicle.
