Camille Pédarriosse's commitment to the environment, as DDRS representative and educational engineer at the Arts et Métiers campus Arts et Métiers , is not the result of a sudden epiphany, but rather a sensitivity that has gradually become part of her academic and professional career.
The Bordeaux University Innovation Cluster, coordinated by the University of Bordeaux as the lead partner, aims to accelerate the region's innovation momentum by unlocking the full potential of public research stakeholders. As a partnership-based cluster, it is committed to creating fertile ground for innovation, understood as the transformation of research results into solutions with a positive impact on human societies and natural ecosystems, by supporting researchers and their projects.
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:
This program supports an action plan defined for the first four years.
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.
On October 17, 2018 , Arts et Métiers launched an industrial chair in Lille with Valeo dedicated to studying nonlinear vibration phenomena in future automotive transmissions in order to improve passenger comfort.
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.
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.
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.
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."

The context surrounding the ELF (Evolutive Learning Factory project and its rollout on the Aix-en-Provence campus represents a real opportunity to bring together teaching and research activities through a common thread running from ideation to design and then to implementation (machining, plastic deformation, and casting) to the analysis of the mechanical properties of components and the control of systems and their durability and life cycle analysis.
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 "Vibroacoustics of electric powertrains."
Supported by Arts et Métiers its subsidiary AMVALOR, this new chair is fully in line with the challenges of the transition to quieter and more efficient electric mobility.
Since 2018, Valeo and Arts et Métiers on a first chair dedicated to " Nonlinear dynamics for the absorbers of the future. " Conducted on the Lille campus, this work has demonstrated the teams' ability to transform fundamental research into high value-added industrial innovations, drawing on the expertise of Professor Olivier Thomas at the Laboratory of Engineering of Physical and Digital Systems (LISPEN).
Building on these results, the partnership is entering a new phase with the creation of a second chair, also involving the Lille Laboratory of Electrical Engineering and Power Electronics (L2EP), with Professor Christophe Giraud-Audine. The objective: to control and reduce residual noise from electric machines and gearboxes, a key issue for the acceptability of electric vehicles.
As Hervé Mahé, Noise and Vibration Expert at Valeo and Deputy Director of the VIBRACCE Chair, explains:
These characteristic whistling noises, easily picked up by the ear and unpleasant for passengers, undermine one of the advantages most sought after by buyers: silence.
With the electrification of powertrains, acoustic comfort is becoming a determining factor.
If NVH (Noise, Vibration, Harshness) exceeds a critical threshold, it can compromise the acceptability of this type of engine among users. As Christophe Giraud-Audine, lecturer-researcher at L2EP and deputy director of the VIBRACCE chair, explains:
Reducing and controlling noise from electric drive trains requires solutions that combine mechanical and electrical expertise. In the course of our work between 2018 and 2025, we have begun to combine mechanical solutions with electromechanical assistance, also drawing on the expertise of L2EP.
Until 2032, the LISPEN and L2EP teams will pool their expertise in numerical computation, vibration mechanics, electrical engineering, and experimental know-how, while Valeo will contribute its in-depth knowledge of the market and its testing, computation, and design resources.
The chair's work will focus on two main areas:
Predict: develop electromagnetic-mechanical simulation tools capable of anticipating vibrations and noise from the design phase of motors and their power supply strategies;
Take action: propose innovative solutions for electrical control and active or passive noise and vibration reduction, such as piezoelectric absorbers, viscoelastic materials, and metamaterials.
The chair program includes at least six doctoral theses, a postdoctoral project, the recruitment of a research engineer, as well as training and scientific dissemination activities.
As Olivier Thomas, professor and researcher at LISPEN, who initiated this collaboration, and deputy director of the VIBRACCE chair, explains:
Acoustic comfort has become a key success factor for electric vehicles. Today, we are taking another step forward to continue supporting Valeo's technological leadership in electric mobility.
