应用THUMS行人有限元模型，进行行人与速度为20、30、40和50km/h的中型轿车、微型轿车、厢式车和SUV等4类不同前部结构车辆碰撞仿真，分析行人胸部动力学响应和胸部碰撞条件以及胸部变形模式和肋骨压缩量等损伤。结果表明，汽车前部结构对行人动力学响应和胸部碰撞速度有重要影响；汽车前部结构的刚度分布是影响胸部肋骨压缩量和变形模式的主要因素。

With THUMS pedestrian FE model, simulations on vehicle-pedestrian crash are conducted for four types of vehicles ( medium sedan, minicar, van and SUVs) with different front-end structures at a impact speed of 20 , 30 , 40 and 50 km/h to analyze pedestrian chest dynamic response and chest impact conditions as well as the chest deformation modes and injuries of pedestrian including rib deflections. The results demonstrate that the front-end structure of vehicle has significant effects on the dynamic response and chest impact speed of pedestrian and the stiffness distribution of vehicle front-end structure is a major factor affecting the rib deflections and chest deformation mode of pedestrian.
