Characteristics of train passages over slab tracks from measurements and different track-soil models - Damage detection and ground vibration reduction
Lutz Auersch
- 01 Feb 2020
TL;DR: In this paper, the characteristics of train passages over intact or damaged slab tracks on different soils have been calculated by the finite element boundary element method or the wavenumber-domain method.

Antonio Romero Ordóñez,Pedro Galvín,José Domínguez Abascal +2 more
- 01 Jan 2010
TL;DR: In this article, a general and fully three dimensional multi-body-finite element-boundary element model was formulated on time domain to predict vibrations due to train passage at the vehicle, the track and the free field.

Haoran Lu,Zhigang Cao,Li Xiao,Yuanqiang Cai,Yifei Xu +4 more
TL;DR: Researchers propose a meta-rod with compression springs and external fixed supporting to attenuate low-frequency waves, analytically deriving its dispersion relation and demonstrating bandgap properties and wave attenuation through numerical methods, enabling effective vibration mitigation at low frequencies.

Modelling vibration from surface and underground railways as an evolutionary random process
Mohammed Hussein
- 01 Jul 2010
TL;DR: In this paper, ground-borne vibration from trains is modelled as an evolutionary random process, where transfer functions between the axles of a moving train and a fixed observation point vary with time.

Digital simulation of random processes and its applications
Masanobu Shinozuka,C.-M. Jan +1 more
TL;DR: In this article, the authors presented an efficient method for digital simulation of general homogeneous processes as a series of cosine functions with weighted amplitudes, almost evenly spaced frequencies, and random phase angles.

An Introduction to Random Vibrations, Spectral and Wavelet Analysis
David Newland
- 01 Dec 1993
TL;DR: In this paper, the authors introduce the idea of joint probability distributions and average for linear systems and their response to random vibrational signals. But they do not discuss the relationship between these distributions and the average.

Modelling of Railway Track and Vehicle/Track Interaction at High Frequencies
Klaus Knothe,S L Grassie +1 more
TL;DR: A review of dynamic modelling of railway track and of the interaction of vehicle and track at frequencies which are sufficiently high for the track's dynamic behaviour to be significant is presented in this paper.

Vertical dynamic interaction between train and track influence of wheel and track imperfections
Jens C. O. Nielsen,A. Igeland +1 more
TL;DR: In this article, the vertical dynamic behavior of a railway bogie moving on a rail is investigated for sleepers resting on an elastic foundation, and the transient interaction problem is numerically solved by use of an extended state-spacer vector approach in conjunction with a complex modal superposition for the track.
