Abstract:

To achieve lateral displacement control of pure electric vehicle models during the safety development process for small offset frontal collisions, a combined simulation and experimental approach ware employed to identify the key structural factors influencing lateral displacement, and to investigate the design methodology and evaluation metrics for front compartment configurations associated with such displacement behavior. Taking a certain type of pure electric architecture sedan of the company as an example, an optimization plan was designed. The results indicate that the proposed scheme increases the lateral displacement of the vehicle during collision disengagement by 236 mm, reduces the maximum structural intrusion by 119 mm in the structural rating assessment, achieves controlled vehicle sideslip. And the G rating is met, validating the effectiveness of the evaluation index, and providing a valuable reference for the development of small-overlap safety strategies in new energy vehicle programs.
