In partnership with the French National Centre for Scientific Research (CNRS), the Ecole Centrale de Lyon (ECL), the École Nationale des Travaux Publics de l'État (ENTPE), the Institut National des Sciences Appliquées (INSA) in Lyon and Université Claude Bernard Lyon 1 (UCBL), PSA Peugeot Citroën is officially inaugurating the Vibro-Acoustic-Tribology@Lyon (VAT@Lyon) OpenLab.

The ceremony will be held today, as part of the first meeting of the OpenLab's steering committee. It will officially recognize the turning point reached in 2012, with the creation of the OpenLabs network, in the partnership relations forged between PSA Peugeot Citroën and the leading Lyon-based scientific research laboratories working in the areas of acoustics, vibration and tribology (the science of friction, wear and lubrication).

Guided by a scientific research programme defined collectively by these well-known Rhône-Alpes-based laboratories and by the PSA Peugeot Citroën Research and Advanced Engineering Department (DRIA), VAT@Lyon brings together the capabilities of researchers from the following laboratories: Mécanique des fluides et d'Acoustique (LMFA, a joint ECL/CNRS/LYON1/INSA Lyon/UJM unit), Tribologie et Dynamique des Systèmes (LTDS, a joint ECL/CNRS/ENISE unit), Génie Civil et Bâtiment (LGCB, a ENTPE unit), Mécanique des Contacts et des Structures (LAMCOS, a joint INSA/CNRS unit) and Vibrations et Acoustique (LVA, an INSA Lyon unit). Institut Carnot Ingénierie@Lyon (I@L) is also a member of the OpenLab.

In particular, this geographically targeted and topic-specific partnership is designed to expand PSA Peugeot Citroën's capabilities for innovation and proficiency in automotive technologies over the medium to long term, and to enable the laboratories to capture the value of their research by transforming their findings into industrial applications.

The VAT@Lyon OpenLab's scientific programme is structured around nine research and innovation topics, which are being explored across the different research teams. Together, they cover the very wide range of applications that could potentially be developed through the organisation's scientific disciplines.

Key application objectives include:

  • Reducing energy loss due to engine friction.
  • Reducing vibrations with innovatively engineered wave traps.
  • Managing and controlling the vibroacoustics of rotating components, such as engines, gearboxes and gear transmissions.
  • Physically modelling complex automotive systems, displaying, for example, chaotic behaviour.
  • Optimising the design of radically new vehicle shapes, including sensory issues dealing with motorists' auditory perceptions and aerodynamic noise.
