WORKSHOP
Fatigue in Automotive parts: challenges when facing lightweight construction on chassis parts
January 16th | 9.00h - 13.30h CET
Venue: Eurecat Manresa, Plaça de la Ciència, 2, 08242 Manresa
The Fatigue4Light project held an industrial workshop to showcase the challenges within lightweight construction for chassis parts, emphasizing fatigue testing, materials, and methodologies to optimize durability.
During the event, our panel of experts addressed the complexities of fatigue in automotive parts, spanning from material science (microstructure influence), testing methodologies, numerical formulations, to practical applications in safety components and hot stamping processes.
The workshop not only emphasized the significance of understanding fatigue in materials, but also showcased innovative strategies and advancements contributing to the future of durable lightweight automotive design.
ABOUT THE PROJECT
The Fatigue4Light project is developing lightweight solutions adapted to the chassis parts of Electric Vehicles to enhance weight reduction compared to current solutions and increase vehicles’ safety due to reduced sprung mass. The project is focused on the development of new tests and computer simulation methods to better estimate the fatigue life of chassis components and to select the optimal materials for lighter vehicle chassis.
Fatigue4Light is one of the first projects tackling weight reduction in automotive chassis parts, which is a necessary step to further progress in electric vehicle lightweighting, as reduction of vehicle weight impacts positively in CO2 emissions, electric vehicle autonomy, driveability and security.
