为探究电动自行车骑车人在汽车碰撞过程中的动力学响应过程,基于国家车辆事故深度调查体系(NAIS)中13起汽车与电动自行车碰撞事故案例,运用多刚体动力学仿真软件Pc-Crash进行事故重建,分析车型、碰撞类型和碰撞速度对碰撞过程中电动自行车骑车人动力学响应的影响。结果表明,骑车人的动力学响应与汽车车型有明显的相关性;在不同碰撞类型情况下,骑车人的动力学响应随着碰撞速度的变化有所差异;在碰撞事故中,骑车人的头部损伤随着碰撞速度的增加而增加。
In order to explore the kinetic response of electric bicyclists in the process of car collision, based on the case of collision of 13 cars and electric bicycles in the National Vehicle Accident Depth Investigation System (NAIS), the multi-body dynamics simulation software Pc-Crash The accident reconstruction was carried out to analyze the influence of vehicle type, collision type and impact velocity on the dynamic response of cyclists. The results show that the dynamic response of the rider has a significant correlation with the car model. Under different collision types, the rider’s dynamic response varies with the collision speed. In the collision accident, the rider Human head injuries increase with increasing collision speed.
