COngrès internationale sur les matériaux pour la mobilité
Transvalor participe à NeMMo 2022, congrès international sur les Nouveaux Matériaux pour la Mobilité du Futur. Cette conférence scientifique organisée par la SIA (Société des Ingénieurs de l'Automobile) et la SFIP (Société Française des Ingénieurs des Plastiques) se tient les 6 et 7 Juillet à Nantes, France.
Rassemblant des experts des industries de l'automobile et des matériaux, NeMMo est l'opportunité de débattre sur l'innovation dans le domaine de la fabrication de composants légers, l'utilisation de matériaux recyclés, le développement durable, l'économie circulaire et l'e-mobilité. Les rencontres, conférences et exposition permettront aux participants d'imaginer la mobilité du futur.
Conférence sur l'optimisation paramétrique du procédé de chauffe par induction
Notre Chef de Produit Marketing Nadine El Kosseifi tiendra une conférence en anglais en collaboration avec NTN-SNR :
- Benefits of the Parametric Optimization in the Induction Heating process
"The challenge of the automotive market engineers is to find innovative technical solutions to deal with the new challenges of electric vehicles.
NTN uses the FORGE® software to simulate the induction hardening process used in manufacturing bearing rings. Recently innovative bearings have been designed and manufactured by NTN. Due to electric vehicles technical requirements, these new wheel bearings and transmissions need to be more compact to be installed in a limited space and at the same time to fully respect a high level of customer expectations. During manufacturing these new bearing rings, the induction hardening process ensures a high hardness on the ball-raceway contacts while maintaining sufficient ductility elsewhere, the difficulty resides in quantifing instantaneously the influence of the inductor geometry and the current on the heated affected zone. To overcome this difficulty, NTN takes benefits from FORGE® parametric optimization coupled with CAD software to reach a given microstructure in a specific zone of the part. After having found the best configuration, a sensitivity test is done around this configuration thanks to a design of experiments. The goal is to build a metamodel able to catch the effect of process deviation without running another simulation. Thanks to this metamodel, it is possible to quantify instantaneously the influence of the inductor geometry and current on the heat affected zone. Through this case, the parametric optimization module integrated in FORGE® software and the coupling between the electromagnetic, thermomechanical, and metallurgical phenomena needed to simulate the induction hardening process will be reviewed."
