Abstract

Abstract: With a frontal 40% overlap deformable barrier crash as example, a multiobjective reliability optimization on the structure parameters of car body is conducted by using technologies of the design of experiment, RBF metamodel and multiobjective reliability analysis. The results show that after optimization, the structure of car body meets the requirements of crashworthiness and lightweighting, with the reliability of structure enhanced, providing an effective reference for the design of car body structure.
