Head Injury Criterion of Vietnamese Pedestrian Struck by a Sedan

Ly, Hung Anh / Nguyen, Phu Thuong Luu

Crash test simulation using the finite element method has become popular in the automobile industry because of its feasibility and cost-saving. The majority of finite element dummy models used in the crash simulation are built based on anthropometrical and biomechanical data of the USA and European bodies. V-dummy is scaled from the Hybrid III dummy model to suit Vietnamese anthropometry. Head injury risk of a pedestrian involved in a frontal and two corners impact position with a sedan is studied. Impact speeds are set 20, 30, 40, 50, 60 km/h. Impact angles are varied from 0°, 45°, and then 90°. A total of forty-five simulation cases are conducted to investigate the head injury by using HIC (Head Injury Criterion). When struck by a sedan, the head will hit on the car’s windshield first (named car impact) and then fly in the air later before impacting to the ground (named ground impact). This research is limited to car impact. The position of head impact on the car strongly depends on the impact angle. When a pedestrian is hit by a Sedan at angle 90°, the shoulder strike on the car bonnet before the head, it causes HIC in impact angle 90° is lower than 0° and 45°. For this car impact duration, the HIC value will increase with the impact speed.
