Investigation of the Effect of Stiffness Characteristics of Vehicles on Pedestrian Pelvis and Lower Limb Injury Measures

車体前部荷重特性が歩行者腰部・脚部傷害指標に与える影響

A vehicle model with high generality and repeatability would be necessary to validate injury assessment tools for a pedestrian in a comprehensive and precise manner. The current study performed car-pedestrian impact simulations using vehicle front end models with changeable stiffness characteristics along with a human FE model. The results of the impact simulations were analyzed to investigate the levels of reproducing stiffness characteristics of vehicle front end structures that are necessary to accurately reproduce pedestrian pelvis and lower limb injury measures.歩行者の傷害評価ツールの妥当性を網羅的かつ精度よく検証するには，汎用性・再現性の高い車体モデルが必要である．本研究では，荷重特性を変更可能な車体前部モデルと人体FEモデルとの衝突シミュレーションから，歩行者の腰部・脚部の傷害指標を再現するために必要な車体荷重特性の再現レベルについて検討した．
