Title
(EN) INTEGRATED ENERGY ABSORBING CASTINGS
(FR) PIÈCES COULÉES INTÉGRÉES D'ABSORPTION D'ÉNERGIE
Abstract
(EN) An integrated energy absorbing system of a vehicle with a front integrated energy absorbing casting and a back integrated energy absorbing casting. Each front and back casting is a single unified casting that makes up the integrated energy absorbing system. Ribbed sections such as "I" sections and "C" sections make up the castings and are formed from a variety of different techniques and/or formings such as cutout, waveform profile, tapering, flaring and/or rib spacing. Additional sections such as closed section castings may also be integrated in the integrated energy absorbing system.
(FR) Un système intégré d'absorption d'énergie d'un véhicule doté d'une pièce coulée intégrée avant d'absorption d'énergie et d'une pièce coulée intégrée arrière d'absorption d'énergie. Chaque pièce coulée avant et arrière est une seule pièce coulée unifiée qui constitue le système intégré d'absorption d'énergie. Des sections nervurées telles que des sections « I » et des sections « C » constituent les pièces coulées et sont formées à partir d'une variété de différentes techniques et/ou formages tels que : découpe, profil de forme d'onde, conicité, évasement et/ou espacement de nervure. Des sections supplémentaires telles que des pièces coulées à section fermée peuvent également être intégrées dans le système intégré d'absorption d'énergie.
