摘要：	The finite element model of a domestic miniature pure electric vehicle is established by using CAE software.According to the requirements of IIHS evaluation system,25%overlapping offset collision simulation is carried out.According to the simulation results,the deformation of the car body structure and the intrusion of each measuring point during the collision process are analyzed.Aiming at the existing problems in the structure crashworthiness of the vehicle,structural improvement measures are put forward,including structural improvement and material strengthening.The optimized model is simulated again with 25%small offset collision.The optimized scheme can significantly improve the crashworthiness of the car body structure and greatly reduce the invasion of the passenger compartment.At the same time,full-width frontal impact and 40%offset impact conditions will be validated.By comparing the changes of body deceleration and intrusion volume of main observation points,it can be concluded that the improved body stiffness is reasonable.
