An experimental exploration of the properties of random frequency response functions
(2021-01)
Article
Restricted access - publisher's policyThe vibro-acoustic analysis of complex structures over a broadband frequency range is an extremely challenging problem that may often require the use of a hybrid deterministic-statistical approach. Due to manufacturing ... -
Numerical validation of a hybrid approach for the assessment of vibrations and re-radiated noise in buildings due to railway traffic
(2020-12-25)
Article
Open AccessIn this paper, a hybrid experimental/numerical methodology for the assessment of railway induced ground-borne noise and vibration in buildings based on experimental measurement in the ground surface is proposed and validated. ... -
Prediction of mechanical properties of human rib cortical bone using fractal dimension
(Gordon and Breach Science Publishers, 2020-10-26)
Article
Restricted access - publisher's policyA large number of post mortem human subjects was used to investigate the relation between the micro-structure of rib cortical bone and the mechanical properties using Fractal Dimension. Uniaxial tensile tests were performed ... -
Investigation on electromagnetic vibration energy harvesting in water distribution control valves
(2020)
Article
Open AccessControl stations of a water distribution system monitor several variables such as the pressure, the flow, and the quality of water. For these monitoring tasks, wireless sensor networks with ultra-low power consumption ... -
Nonlinear impact of traction rod on the dynamics of a high-speed rail vehicle carbody
(Springer, 2020-12)
Article
Restricted access - publisher's policyThis paper focuses on the bogie-carbody nonlinear dynamic interaction of a Shinkansen high-speed rail vehicle. The Euler-Bernoulli beam model is used to simulate vertical elastic vibrations of the carbody. As a novelty, ... -
Traffic noise assessment based on mobile measurements
(2021-01)
Article
Restricted access - publisher's policyContinuous noise monitoring based on mobile systems could provide a quick feedback to assess the effect of policies implemented by authorities to mitigate noise pollution. The present research verifies that mobile measurements ... -
A methodology based on 2.5D FEM-BEM for the evaluation of the vibration energy flow radiated by underground railway infrastructures
(Elsevier, 2020-07-01)
Article
Restricted access - publisher's policyIn this paper, a comprehensive numerical approach for modelling track/tunnel/soil systems in the context of ground-borne railway-induced vibration problems considering a full-space model of the soil is proposed. All the ... -
An efficient experimental methodology for the assessment of the dynamic behaviour of resilient elements
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-06-27)
Article
Open AccessThe assessment of the dynamic behaviour of resilient elements can be performed using the indirect method as described in the standard ISO 10846-3. This paper presents a methodology for control the error on the estimation ... -
A numerical and scaled experimental study on ride comfort enhancement of a high-speed rail vehicle through optimizing traction rod stiffness
(SAGE PUBLICATIONS INC, 2020)
Article
Open AccessIn this research, the effect of rail vehicle carbody’s flexural modes on the ride comfort of an example high-speed railway vehicle is investigated. The vehicle is modeled as a rigid multi-body system, where the rigid body ... -
Development of a hybrid FE-SEA-experimental model
(2019-12-01)
Article
Restricted access - publisher's policyThe vibro-acoustic response of complex structures with uncertain properties is a problem of great concern for modern industries. In recent years, much research has been devoted to the prediction of this response in the ... -
Experimental and numerical assessment of local resonance phenomena in 3D-printed acoustic metamaterials
(2020-04)
Article
Open AccessThe so called Locally Resonant Acoustic Metamaterials (LRAM) are a new kind of artificially engineered materials capable of attenuating acoustic waves. As the name suggests, this phenomenon occurs in the vicinity of internal ... -
Control of ground-borne underground railway-induced vibration from double-deck tunnel infrastructures by means of dynamic vibration absorbers
(2019-08-23)
Article
Restricted access - publisher's policyThe aim of this study is to investigate the efficiency of Dynamic Vibration Absorbers (DVAs) as a vibration abatement solution for railway-induced vibrations in the framework of a doubledeck circular railway tunnel ...
