Abstract:To achieve lateral displacement control of pure electric vehicle models during the safety development process for smallofset frontalcollsions,a combined simulationand experimental approach wareemployedto identifythe keystructuralfactors influencing lateral displacement,andto investigate the designmethodology and evaluation metrics for front compartment configurations associated with such displacement behavior.Takinga 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 236mm ,reduces the maximum structural intrusion by 119mm in the structural rating assessment, achieves controlled vehicle sideslip.And the Grating ismet,validating theeffectivenessof theevaluation index,and providingavaluable reference for the development of small-overlap safety strategies in new energy vehicle programs.
