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.
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."
