Predicting and Eliminating Squeak & Rattle Noise in Vehicle Interiors with PSA Peugeot Citroën

Tuesday, December 13, 2016 at 10 a.m. U.S. EST

For car makers, squeak and rattle phenomena represent a significant problem as many customers will interpret the noise as a general lack of quality in the product. The industry is eager to better understand and predict these phenomena so interior noise can be reduced and ride quality can be improved. 

During the  development  of  new  vehicles,  PSA  Peugeot Citroën Group (PSA) wanted to take the lead in using simulation technology to detect squeak and rattle noise problems, before physical testing was possible. The initiative led to a collaboration between PSA’s Method Development Engineering team and Altair ProductDesign to explore the use of simulation technologies and numerical optimization methods at an early stage of development. This 60-minute Webinar, jointly presented by PSA and Altair, discusses the project and its progress, describing the results achieved through the application of an “E-Line method” approach and detailing how the newly established processes have been integrated into PSA’s existing Virtual Development Process (VDP).

An audience Q&A follows the technical presentation.


Ismail Benhayoun, Business Development Manager, Altair

Ismail Benhayoun is one of the Automotive Business Developers at Altair, which he joined in 2012. His role consists of method and business development for the automotive industry with a strong focus on squeak and rattle simulation and virtual development. He started working in the CAE field in 2009 at GM Europe/Saab Automobile, focusing on FEM simulations and the correlation on interior parts as well as the co-development and implementation of squeak and rattle simulation. He holds a mechanical engineering degree from ESSTIN and an MSc in automotive engineering from Chalmers University of Technology.

Sébastien Gourg, CAE Methods, Expertise & Support Engineer, PSA Peugeot Citroën

Sébastien Gourg has been the Virtual Approach Development Leader at PSA Group since 2014, developing and implementing a virtual approach to detect squeak and rattle issues in PSA processes. Previously he was the Engine Family Technical Leader at PSCO, an Acoustic Specialist at Faurecia Exhaust System, and a CAE Engineer, Optimization, at Faurecia. Sébastien has a master’s degree in project management from the University of Quebec and a mechanical engineering degree from ISMANS.
