Railway Vibrations
Suggestions for preliminary Reading:
Graduated from
the Faculty of
Engineering at the
University of Mons
in mechanical
engineering in
2002, and worked
as a research and
teaching assistant
at the university. He obtained his PhD
from the same university in 2009. He is
appointed to the academic staff of the
Department of Mechanical Engineering at
the University of Mons; since 2010 he has
been a senior research assistant, a senior
lecturer and an associate professor. He
teaches engineering vibration, structural
analysis, computer-aided kinematics
and dynamics of mechanical systems,
machine noise, and safety-related control
systems. His research interests are the
environmental impact of vibrations
induced by railway traffic, the simulation
of multibody models, signal processing for
effective vibration analysis, soil-structure
interaction and modal analysis.
Compared to railway dynamics that mainly focuses on vehicle
issues such as comfort and stability, railway vibrations include
not only the vibration feelable inside the vehicle but also the
vibrations transmitted to the track and ground. Since the rail
network needs more and more to be developed over long
distances and within cities, it represents a more sustainable
transport option. However, vibrations are seen as a negative
environmental consequence. Compared with airborne noise,
the related problem of ground vibration is much more complex.
The properties of the ground vary significantly from one
location to another. There is no common assessment criterion
or measurement quantity and no equivalent to the noise
maps. Ground-borne vibration is transmitted into buildings
and perceived either as feelable whole-body vibration or as low
frequency noise; it can also affect sensitive equipment but it is
generally at a level that is too low to cause structural or cosmetic
damage to buildings. A review is given of evaluation criteria for
feelable vibration, empirical and numerical prediction methods,
the main vehicle, track and soil parameters and configurations
that can affect the vibration levels and a range of possible
mitigation methods. An in-depth discussion is then presented
related to the evolution of numerical models, with analysis of the
suitability of various modelling approaches for analysing vehicle
effects.

Vibrations caused by surface or underground railway traffic may
spread throughout the building structure being perceived as
annoying vibration or as secondary structure-borne noise. The
induced vibrations depend on the characteristics of the emission
source, the transmission through the ground, the coupling
of the building foundation to the subsoil, and the vibration
spread within the building structure. The frequencies involved
range from 10 to 100 Hz, thus requiring complex computer-
aided analyses for the reliable prediction of the vibration level.
Measurements are indispensable part of such investigations.
Simple and advanced prediction schemes for the different parts
of the vibration propagation chain are elucidated. Appropriate
countermeasures at the source, along the transmission path,
and at the place of immission in the building are described.
Finally, some challenging case-studies are presented showing
the application of the design concepts in practice.

Seismic isolation is a mature technology, used in Europe since the
1970s, but still rarely used and not well known in some country,
despite its advantages and cost effectiveness have been fully
demonstrated in 40 years of research and application. The main
objective of the course is to introduce to the basic principles of
seismic isolation and to its implementation into real structures, in
particular buildings. The fundamental requirements of Eurocode
8 (EN1998-1) for design of seismically isolated structures will be
given. The most used types of isolation devices will be presented;
the physical behaviour, the analytical modelling, the main
experimental investigations and some example of application are
described for each of them. The requirements of the European
Standard EN 15129 “Anti-seismic devices” will be discussed both
for isolation devices and for other anti-seismic devices, such as
energy dissipation devices, that sometimes are used together with
isolators as components of the seismic isolation system.

The lecture introduces the concept of pillared phononic crystals
and metamaterials, which represent an emerging class of artificial
materials consisting of pillars standing on a substrate or a plate.
Under appropriated geometries, such structure has the ability to
exhibit both Bragg and hybridization band gaps. These physical
properties make the pillared structure useful for a variety of
applications covering a wide range of length scales and different
disciplines in applied physics and engineering. Pillared surfaces
allow the control and manipulation of Rayleigh and Love waves
as well as Lamb waves in plates, for frequencies ranging from Hz
to several GHz. We will provide an overview of the fundament and
development of the concept of pillared meta-materials, then a
synopsis of some of the state-of-the-art research that involves the
utilization of pillars in different contexts, among: (i) Fundamental
vibrational and propagation properties; (ii) Metamaterial’s aspect
for pillared phononic plates with widening/lowering hybridization
band gap [1]; (iii) Wave steering functions in pillared metasurface
[2]; (iv) Super-resolution focusing; (v) Topologically protected edge
states in pillared phononic plates; (vi) Liquid/solid interaction for
sensing; (vii) Phonon/plasmon interaction for optomechanical
applications.
