采用多体动力学软件开发建立的车辆行人碰撞仿真模型,模拟了碰撞事故中行人的动态响应,确定和分析了颅脑损伤相关的主要碰撞生物力学参数以及影响颅脑损伤的汽车前部结构主要设计参数.研究结果表明,限制车辆行驶速度、适当减小汽车前部结构刚度以及适当提高发动机盖缘高度可以很大程度上降低行人的颅脑损伤.
The simulation model of vehicle pedestrian collision developed by multi-body dynamics software was used to simulate the dynamic response of pedestrian in collision accident. The main collision biomechanical parameters related to brain injury were identified and analyzed, as well as the main front structure of automobile affecting brain injury The results show that the limitation of the vehicle speed, the proper reduction of the stiffness of the front of the vehicle and the proper increase of the height of the engine cover can greatly reduce the head injury of pedestrians.
