- 摘要:
- 为研究行人与轿车正碰后卷绕型运动形态规律以及行人损伤情况，基于PCCrash和MADYMO软件进行仿真分析。分析不同发动机罩倾斜程度对行人抛距的影响，以及不同车速、行人走向、前挡风玻璃倾角对行人头部、胸腔的损伤影响，最后通过CIDAS数据库中的3起真实案例进行验证。结果表明：分段抛距公式不仅能反映行人抛距变化趋势，而且在2个分段范围内均能较好地拟合实际抛距，平均误差为4.23%，实际案例验证的结果误差在5%以内，证明实验方法的准确性。
- Abstract:
- In order to study the winding motion pattern and pedestrian injury after the direct collision between pedestrian and car,the simulation analysis was conducted based on PC-Crash and MADYMO software.The winding motion process was simplified into three stages,and the formulas of segmented throw distance under different collision speeds and pedestrian orientations were obtained according to the separation pattern of pedestrian and vehicle.The influence of different tilt degrees of engine hood on the throw distance of pedestrian was analyzed,as well as the influence of different vehicle speeds,pedestrian orientations and front windshield inclination on the head and chest injuries of pedestrian.Finally,it was verified by three actual cases in the CIDAS database.The results showed that the obtained segmented throwing distance formulas could not only reflect the change trend of pedestrian throwing distance,but also better fit the actual throwing distance within the two segment ranges.The average error was 4.23%,and the result error of the actual case verification was within 5%,which proved the accuracy of experimental method.
