摘　　要：本文基于2020版E-NCAP正面MPDB工况对江铃某款已上市SUV车型进行了实车试验和碰撞仿真,评估基础车碰撞相容性。并对比MPDB工况与ODB偏置工况的性能差异,探讨优化碰撞相容性的应对策略。提出一种车体前端关键传递路径优化设计方案,可大幅降低碰撞相容性罚分,为后续新车型设计提供参考依据。Based on the 2020 E-NCAP MPDB impact test,a physical vehicle test and CAE simulation of a listed SUV model of Jiangling Motors were carried out to evaluate the compatibility of the base model.Comparing the performance diff erence between MPDB and ODB test,the article presents the countermeasures for optimizing the compatibility.An optimization design scheme for the key load path of the front end of the vehicle body is proposed,which can greatly improve the compatibility performance and provide reference for the new type model design.
