As part of the research programming law and the France 2030 plan, the University Innovation Cluster led by the University of Bordeaux brings together 14 academic institutions and two subsidiaries associated with 34 partners in the region. With this diverse group of players and a long shared history, it will lead to the development of collaborative research with businesses and the creation of startups (known as "deep tech") that are driving disruptive innovation.

The project is organized around three strategic areas:

• streamline interactions between academic institutions and socio-economic actors with new platforms, new processes, and new tools. The impact will be optimized resources, time savings, and greater stakeholder satisfaction;
• inspire researchers to innovate, in particular by raising their awareness of regional socio-economic issues. The impact will be to increase opportunities for collaborative research and pre-maturation and maturation activities;
• promote partnerships with socio-economic stakeholders and the creation of innovative businesses. The impact will be to increase the creation of deep tech startups and the success rate of innovations.

This program supports an action plan defined for the first four years.

Arts et Métiers, one of the 16 founding members

Arts et Métiers one of the 16 founding members of the Bordeaux University Innovation Cluster, alongside the University of Bordeaux, Bordeaux Montaigne University, the CNRS, Inserm, Inrae, the Inria center at the University of Bordeaux, Bordeaux INP, Sciences Po Bordeaux, the Ecole Nationale Supérieure des Sciences Agronomiques (BSA), Estia, the Institut d'Optique Graduate School (IOGS), the Centre hospitalier universitaire (CHU) and Bordeaux, the École Nationale Supérieure d'Architecture et de Paysage (ENSAP) in Bordeaux, SATT Aquitaine Science Transfert (AST) and ADERA.

The 34 partners associated with the PUI are competitiveness clusters, clusters, technology resource centers, industrial technical centers, economic development agencies, etc. Also included are: the French Alternative Energies and Atomic Energy Commission (CEA), the French National Office for Aerospace Studies and Research (ONERA), the Bordeaux University Foundation, the Nouvelle-Aquitaine Region, and Bordeaux Métropole.

Arts et Métiers Valeo, partners in the industrial chair dedicated to the vibration dynamics of automotive transmission chains

The "Nonlinear Dynamics for Future Absorbers" Chair is a structuring partnership betweenArts et Métiers, Valeo, AMValor, and the LISPEN laboratory. This chair was conducted over the period 2018-2023.

Scientific officer

To reduce fuel consumption and control environmental impact, car manufacturers are developing internal combustion engines with smaller displacement. This reduction leads to increased engine acyclism, which causes vibrations that reduce component life and acoustic comfort. 

Furthermore, in the case of electric or hybrid electric/thermal vehicles, similar vibration problems arise and lead to significant noise pollution.

The research conducted by the "Nonlinear Dynamics for Future Absorbers" chair aimed to develop various techniques and devices for reducing torsional vibrations in the transmission chain by improving existing techniques or developing new strategies.

These main achievements are:

5 theses defended:

• Calculation and optimization of pendulum absorbers in an automotive powertrain (Alexandre RENAULT, 2018)
• Design and calculation of semi-active vibration dampers for automotive powertrains (Michel AULELEY, 2020)
• Calculation, control, and reduction of vibrations and noise in gear transmissions for electric vehicles (Eddy ABBOUD, 2022)
• Design improvements to pendulum absorbers to reduce vibrations in automotive transmission chains (Vincent MAHÉ, 2022)
• Semi-passive torsional vibration control for automotive electric transmissions (Guillaume HAY, 2025)

Automotive News Pace Award 2022

Two of the above theses, written by Alexandre Renault and Vincent Mahé, enabled Valeo to industrialize an innovative pendulum damping system and receive an "Automotive News Pace Award"in 2022. This prestigious award recognizes automotive suppliers for their innovations, technological advances, and commercial performance.

Signing of a new chair covering the period 2024-2030 and focusing on the vibro-acoustics of electric powertrains

After seven years of fruitful collaboration, Valeo and Arts et Métiers and expanding their strategic partnership by inaugurating a new industrial research chair dedicated to "Vibro-acoustics of electric powertrains."
