In the present study, the factors that can affect a pedestrian’s chest injuries by the front configuration of a vehicle were investigated using a finite element analysis. In a bonnet-type car-pedestrian accident, the pedestrian’s chest impacted the bonnet top at a low velocity according to the rotation of the pedestrian's entire body around the car. The stiffness of the bonnet top where the chest impacted was distributed, and thorax deformation was small and uniform. In a one-box type vehicle-pedestrian accident, the pedestrian’s chest was directly impacted by the front of the vehicle at a high velocity. Because the chest was hit by the stiff windshield frame, the thorax was deformed locally. The results showed that vehicle configuration can affect the impact velocity to the chest, and the stiffness of the vehicle structure can affect chest deformation and its mode.

在本研究中，可以影响行人的胸部伤害的车辆前部配置的因素进行了研究，使用有限元分析。在发动机罩型车-行人事故中，根据行人的整个身体围绕汽车的旋转，行人的胸部以低速撞击发动机罩顶部。胸部撞击处发动机罩顶部刚度分布均匀，胸部变形小且均匀。在一箱型车-人碰撞事故中，行人的胸部被高速行驶的车辆正面直接撞击。由于胸部被坚硬的挡风玻璃框架撞击，胸部局部变形。结果表明，车体结构影响胸部的碰撞速度，车体结构刚度影响胸部的变形及其模态。
