Abstract

With the tightening of energy consumption and emission regulations, automotive lightweight is more and more imperative. Herein, A-pillar upper reinforcement using 1700 MPa ultra-high strength steel (UHSS) 3D roll bending was firstly designed and applied to carbon fiber reinforced plastics (CFRP) side frame to achieve extreme lightweight and collision safety performance. The load extraction and subsystem model structure optimization methods were developed to solve the problems of large analysis model and low calculation efficiency in the traditional optimization iteration process. Finally, the application of 1700 MPa UHSS 3D-roll bending A-pillar upper reinforcement onto the CFRP side frame can reduce the weight by 19%, and improve the collision performance effectively.
