摘　　要：基于2013版本EuroNCAP行人保护5星评价标准,建立了某SUV车型前端结构有限元模型,利用头模撞击器,结合试验结果,对该SUV车型行人保护头部碰撞性能进行了试验和仿真分析,同时结合各个碰撞点的局部结构特征,对车身局部进行了有针对性的改进设计。结果表明,优化后的车身结构降低了头部模型碰撞加速度和HIC15值,提高了行人头部保护性能。In this paper, the front end finite element model of a SU~ is built according to EuroNCAP version 2013, this SUV model was tested and simulated for head protection performance with head impactor, in addition, improvement design was made to local body in combination of local structure features of each impact point. The results show that the optimized body structure reduces head model impact acceleration and HIC15 value, pedestrian head protection performance is thus improved.
