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.
