The research in the field of acoustics is focussed on the noise power characterization of combustion engines,
the numerical calculation of sound radiating from ducts and the sound quality of exhaust systems.
Some of the research programs are in collaboration with Bosal
and are funded by the IWT
Sound power measurements on all sorts of equipment (electrical, electromechanical, HVAC)
are performed in the anechoic room for industrial clients.
The research in the field of vibration is mainly concentrated on experimental and operational modal analysis.
Advanced system identification and measurement methodologies have been developed to model the dynamic (vibration)
behaviour of complex mechanical systems starting from input/output or output-only measurements.
These models can be used to solve vibro-acoustical problems in cars, to assess damage
in safety critical airplane components, for flight flutter analysis, ...
The application field is mainly focussed on automotive and aeronautical industry.
Our most important industrial research partners are ASCO Industries
and LMS International
The research is essentially funded by the
Flemish Institute for the Improvement of the Scientific and Technological Research in Industry (IWT
the Fund for Scientific Research - Flanders (FWO
the Research Council (OZR
) of our university and the European community.
Experimental Modal Analysis (EMA, OMA, OMAX)
Most of the research is situated in the field of Experimental Modal Analysis.
Advanced identification techniques - based on Maximum Likelihood concepts - have been developed in order
to improve the experimental modeling of mechanical systems. These techniques can be applied to the so-called
Operational Modal Analysis as well.

Optical Measurement Techniques (OPTIMESS)
Our research group co-ordinates a Scientific Research Networks OPTIMESS, funded by the Fund for Scientific Research (Flanders), for the period 2004-2008.
The aim of this network is to improve communication on scientific developments on optical measurement techniques for the characterization of the static and dynamic behavior of structures and systems.
