Abstract

Abstract

Under the tendency of automotive lightweight, the Body in White (BIW) light weighting job is still significantly meaningful. From aspects of the domestic and abroad research status, structure design, structural analysis, mass comparison analysis, the lightweight of the local structure on car upper body was studied. By incorporating ultra-high-strength steel roll forming 3D tube into Honda Civic 2016 A-pillar and roof rail structure, the original hot stamping reinforcements were replaced. Based on the roof crush test referring to GB 26134—2010, the roof crush performance of the optimized structure was need to be equivalent to the original structure. By comparing the quality, the lightweight effect of the new design with 3D tube inside of the body was obtained. The results prove that new structure with 1 mm gauge and 1 700 MPa Martensitic steel 3D tube shows equal bending stiffness and strength with original structure. A significant mass reduction of 3.23 kg per car can be achieved.
- ultra-high strength steel,
- roll forming,
