An augmented Kalman filter for force identification in structural dynamics
TL;DR: It is shown how, in the collocated case, more accurate results can be obtained with the augmented filter due to its incorporation of modeling errors, while better solutions are produced by classical deterministic methods as Dynamic Programming in which only the forces are estimated, and not the states as well.
Journal ArticleDOI
Ground-borne vibration due to static and dynamic axle loads of InterCity and high-speed trains
Geert Lombaert,Geert Degrande +1 more
TL;DR: In this paper, a solution strategy is presented that allows for the evaluation of the second-order statistics of the response due to dynamic excitation based on the power spectral density function of the track unevenness.
Journal ArticleDOI
The experimental validation of a numerical model for the prediction of railway induced vibrations
TL;DR: In this paper, the authors presented the experimental validation of a numerical model for the prediction of train induced vibrations, where the track geometry is assumed to be invariant with respect to the longitudinal direction, allowing for an efficient solution of the dynamic track-soil interaction problem in the frequency-wavenumber domain.
Journal ArticleDOI
A numerical model for ground-borne vibrations from underground railway traffic based on a periodic finite element–boundary element formulation
Geert Degrande,Didier Clouteau,Ramzi Othman,Maarten Arnst,H Chebli,Ralf Klein,P Chatterjee,Bram Janssens +7 more
TL;DR: In this article, a numerical model is presented to predict vibrations in the free field from excitation due to metro trains in tunnels, where the three-dimensional dynamic tunnel-soil interaction problem is solved with a subdomain formulation, using a finite element formulation for the tunnel and a boundary element method for the soil.
Journal ArticleDOI
A 2.5D coupled FE-BE methodology for the dynamic interaction between longitudinally invariant structures and a layered halfspace
TL;DR: In this paper, a 2.5D coupled finite element-boundary element methodology for the computation of the dynamic interaction between a layered soil and structures with a longitudinally invariant geometry, such as railway tracks, roads, tunnels, dams, and pipelines is presented.
