Introduction

The Department has equipment for vibrations measurements (shakers, microphones, pick-ups, strain gauges, Fourier analyzers, multi-channel data acquisition systems, modal analysis softwares,…) allowing to perform operational vibration analysis and modal analysis (vibrations measurements, industrial vibration issues, experimental modal analysis, vibration levels controls,…).

Design criterias of railed vehicles emphasize logicaly the comfort and the safety of the passengers. In urban areas, they also take into account the vibration impact on the environment. In such a case, the dynamical models of the vehicle, the rail and the ground are coupled. Experimental procedures have been developped to characterize the ground and the rail and obtain the parameters needed to build models. A software allowing to evaluate the vibration impact of urban railed vehicles has been programmed, thanks to a partnership with Bombardier Europe, the STIB and the Walloon region.

 

The Department has also research activities in numerical methods to simulate and optimize dynamical and kinematical behavior of systems. Besides the use of commercial codes, the Service has developped its own home-made software named EasyDyn, based on a generalized coordinates approach. The main applications are about terrestrial transportation (design of the architecture of urban transportation vehicles, transmission components simulation,…) in partnership with Bombardier Europe and AW Europe (tram 2000 of Brussel, LRV Vehicle of Minneapolis, automatic gearbox AISIN AW,…).

 

The study of acoustics is naturally combined with the study of the vibrations. Step by step, the Service spreads its competences to the acoustics and vibro-acoustics. The Service has measurements equipments (omni-directional sources, data acquisition systems, analyzers, microphones, ...) and simulation softwares to study noise issues and illustrate the lessons of acoustics.

Pole SafeDyn

SafeDyn was created in 2005. The purpose of SafeDyn is to gather complementary research teams in the University to build a pole of expertise in the following domains :

- Machines reliability,

- Safety and comfort of the peoples and integrity of goods under severe environmental conditions,

- Control of industrial safety,

- Harmful effect of noise and vibrations on the environment

- Design of mechanical equipments working under severe environmental conditions
