C-NCAP started to assess Hybrid III 5th percentile dummy injury in the rear row in the full frontal 50km/h rigid barrier impact test(FRB)and the frontal 64km/h offset deformable barrier test(ODB)since the year of 2012, This paper studiesthe effect of position of inboard anchorage on the injury numbers of rear dummy(Hybrid III 5th percentile female)in the FRB condition and in the ODB condition when the different rear seatbelt retractor configurations are used, the results indicate that more forward inboard an- chorage point tends to increasehead excursion, reduces chest deflection and possibility of submarining in both FRB and ODB conditions with the different rear seatbelt retractor configurations.

某N1类车型在应对法规GB11551—2014开发过程中,由于受车体纵向设计空间的限制,在进行正面全宽刚性壁障碰撞时,左右纵梁前端吸能盒结构变形与吸能不充分,导致乘员伤害值较大.本文分析该车在碰撞过程中的吸能机理后,在不改变已有结构的基础上,新增加前防撞横梁结构,并基于Ls-Dyna建立前防撞横梁及整车碰撞的有限元仿真模型辅助结构优化设计.通过对比仿真结果,新增加防撞横梁结构后,纵梁前端吸能盒结构
