摘　　要：为了分析散落物在汽车发生碰撞时的分布特征及不同材质类型的散落物对分布特征的影响,为汽车事故再现中的碰撞速度推理提供参考,设计了智能循迹货车和乘用车模型的实车碰撞试验。通过两种类型车辆的完全侧面碰撞试验,模拟分析了事故现场散落物分布面积、质量与碰撞速度之间的关系。研究结果表明:当发生侧面碰撞时,不同材质类型的散落物具有自身的散落特性,其中大豆的散落面积最大,瓜子的散落质量最多,同种材质散落物的散落面积、质量与碰撞速度有着显著的数学关系。In order to analyze the distribution characteristics of the debris in the collision of vehicles and the influence of different types of scattered materials on the distribution characteristics,the real vehicle collision test of the intelligent tracking truck and passenger car models was designed,to provide a reference for the inference of collision speed in automobile accident reproduction.Through the full side impact test simulation of two types of vehicles,the relationship among the distribution area,mass and collision speed of the debris at the accident site was analyzed.The research results show that the debris of different material types have their own scattering trends when a side collision occurs.Among them,soybean has the largest scattered area and melon seeds have the largest scattered mass.There is a significant mathematical relationship between the scattering area and mass of the scattered objects with the same material and the collision velocity.
