LEAM - Laboratori d'Enginyeria Acústica i Mecànica
El LEAM té com a missió la recerca en el control del soroll i les vibracions i traslladar el coneixement adquirit a l'entorn socioeconòmic. La recerca abasta des de la formulació de models analítics i numèrics fins a la validació experimental en plantes pilot i en situacions reals. Els principals camps de treball són la modelització de l'impacte vibratori d'infraestructures, el control actiu de soroll, l'acústica ambiental i la detecció de fallades per emissió acústica.

A 2.5D coupled FEM-BEM-MFS methodology for longitudinally invariant soil-structure interaction problems
(Elsevier, 2021-04)
Article
Restricted access - publisher's policyThis paper is concerned with a new prediction methodology for longitudinally invariant soil-structure interaction problems in elastodynamics. The method uses the finite-element method to model the structure, the boundary-element ... -
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. ... -
Revision of cancellation at the edge approach for active noise barrier
(2020)
Conference report
Restricted access - publisher's policyIn most of the investigations, the active noise barriers are configured placing both secondary sources and error sensors close to the edge of barriers, but it is unclear how far is this approach from the maximum theoretical ... -
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 ... -
Investigate the effect of the active noise barrier on the reduction of noise level at the shadow zone and the neighboring building
(Institute of Noise Control Engineering, 2020)
Conference report
Restricted access - publisher's policyBarriers are among the most widely used strategy to control the ambient noise in the urban areas. However, the previous studies approve the inefficiency of the barriers to degrade low-frequency spectra noise. The technique ... -

Experimental validation of a hybrid FE-SEA-experimental model
(Institute of Noise Control Engineering, 2020)
Conference report
Restricted access - publisher's policyModern manufacturers usually need to know at a design stage if their products will meet certain vibro-acoustic requirements. In many cases the use of physical prototyping becomes significantly expensive, and engineers opt ... -
Uncertainty assessment of a model to predict the vibration induced by train traffic in tunnels
(Institute of Noise Control Engineering, 2020)
Conference report
Restricted access - publisher's policyThe uncertainty assessment of ground-borne noise and vibration predictions is important to reduce risks when decisions are made based on simulation results. In addition, it provides robustness to the prediction framework ... -
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, ...
