First, the dynamic axle loads are computed by solving the train-track interaction problem with a periodic model.
Using a 2.5D model to predict the response during a train passage leads to an overestimation of both train-track interaction forces and free field vibrations.
The aim of this article is to review current knowledge of kinetic variables of the hoof-track interaction and track properties relevant to the objective of minimizing injuries to horses at racing tracks.
Based on simulation of dynamic vehicle-track interaction followed by a discretisation of the conditions in each wheel-rail contact, distributions of rail wear are calculated by the Archard model of sliding wear, while surface initiated rolling contact fatigue (RCF) damage is evaluated by the Palmgren Miner rule and an index building on shakedown theory.
Furthermore, in the Results section you state '[the ADP-dependent Kin3 motor and track] interaction is not important (or does not exist)...'..
Growth of railhead roughness (irregularities, waviness) is predicted through numerical simulation of dynamic train track interaction on tangent track.
Baeza et al. [18] built a model that coupled rotating flexible wheelset and a flexible track model for simulating vehicle track interaction at high frequencies when investigating growth in rail roughness.
The effect of wheelset and track flexibility on dynamics of wheelset track interaction was investigated.
To take consideration of the effect of nonlinearities in the track and in wheel rail contact, train track interaction models in time domain are widely studied today: in [4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14], the train track interaction is defined in time domain with the vehicle and/or the track model defined using the finite element method.
A numerical model for dynamic vehicle track interaction at rail welds with longitudinal surface irregularity is presented.
