摘要
针对汽车冲撞行人抛出速度问题,利用人体直杆模型,运用有关力学原理,得出汽车与行人第一次冲撞后人体的转动角速度和平动速度,进而讨论了不同冲撞车速下人体倒向发动机罩的可能运动状态,结果比较符合实际情况,这对交通事故鉴定工作具有应用价值。
A mechanical shaft model of human body is established to calculate the angular speed and translational speed of the body upon its first collision with a vehicle. The possible moving states of the body collapsing onto the hood at different crashing speeds are then discussed, which is found to agree with the actual circumstances. These results can be used for traffic accident investigations and identifications.
