摘要
利用人体头部生物力学模型研究了行人与车辆前端碰撞时头部损伤。结果表明,在同一目标点进行碰撞时,由于颅骨碰撞位置不同,产生的颅骨损伤也不同,当碰撞位置为额骨和颞骨时存在骨折风险;对于颅脑损伤,随着碰撞位置不同,存在不同脑挫裂伤及脑振荡风险;与EEVC头部碰撞模型对比头部合成加速度曲线趋势一致,发动机罩外板变形接近,HIC15值随着碰撞位置不同,存在较大差异。
A biomechanical model of human head had been used to study the pedestrian head injuries in a vehicle front-end collision. Results show that, for the same collision target, different locations of collision on the skull can result in different types of skull damage. When the frontal and temporal bones are hit, fracture risk may exist. For head injury, as the collision position varies, there are different risks for brain contusion, laceration and concussion. Compared with the results from the EEVC head collision model, the head resultant acceleration curves from the two models show the same trend. Similar results were observed for the deformation of the engine hood outer panel. However, for different collision positions, there exist great differences between their HIC15 values.
