摘　　要：研究了汽车行驶速度及前部结构各设计参数对行人颅脑损伤的影响,讨论了颅脑损伤防护的可行性措施。运用多刚体动力学软件Madymo建立了基于不同车型参数的汽车前部结构数学模型以及行人人体数学模型,进行了车辆-行人碰撞的计算机仿真,并对仿真结果进行了分析研究。研究表明,汽车行驶速度、发动机盖盖沿高度以及发动机盖和挡风玻璃的刚度等参数对行人颅脑损伤影响显著。This study aimed to find out the influences of impact speed, vehicle front structure and stiffness on head injuries and discused the protection measures for skull and brain injury. A parameter study was carried out by using multi-body （MB） dynamic models of pedestrian and vehicles. All the mathematical models were built up using MB program Madymo. The simulation results were analysed and discussed in terms of injury mechanism. The results turn out to be of that vehicle speed, bonnet leading edge height and stiffness of bonnet and windscreen have significant influences on head-brain injuries.
