The development of rail-head acoustic roughness

, 2009
A model of the development of rail-head acoustic roughness on tangent track has been formulated. The model consists of a two-dimensional time domain wheel-rail interaction force calculation, with the normal force used as the input to a two-dimensional ...

The interaction between railway vehicle dynamics and track lateral alignment

, 2016
Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...

Collaboration post‐acquisition: The role of acquirers' motives

Strategic Management Journal, EarlyView.
Abstract Research Summary What role do collaborations with a target's partners play in an acquisition, and how do these collaborations evolve post‐acquisition? Research suggests that these collaborations are an important reason to acquire but often diminish post‐acquisition. But if they tend to diminish, why are they a reason to acquire?

Modelling and simulation of dynamic wheel-rail interaction using a roller rig

, 2012
The interaction between the wheel and rail greatly influences the dynamic response of railway vehicles on the track. A roller rig facility can be used to study and monitor real time parameters that influence wheel-rail interaction such as wear, adhesion,

Analysis of the Impact of Frog Wear on the Wheel–Rail Dynamic Performance in Turnout Zones of Urban Rail Transit Lines

Lubricants
To investigate how severe wear at No. 12 turnout frogs in an urban rail transit line operating at speeds over 120 km/h on the dynamic performance of the vehicle, a vehicle–frog coupled dynamic model was established by employing the 2021 version of ...
