This paper presents the approach of computer simulation to clarify the questions faced by forensic experts about what causes the various injuries characteristic of two motorcycle victims, including the motorcycle driver and the back seat occupant on the motorcycle, and how to exactly confirm which one of them is the motorcycle driver. Two typical motorcycle-car accident cases were reconstructed to analyze the movement and the load of both the motorcycle driver and the back seat occupant in the collision course. In case one, the back seat occupant suffered fatal head injuries when he fell on the ground after being thrown higher than the motorcycle driver over the top of the car. In case two, the compressive force loaded by the right tibia of the back seat occupant was larger and more durative compared with the motorcycle driver; the back seat occupant suffered a bursting fracture injury of his right tibia. These results might be useful for forensic experts in dealing with similar motorcycle-car collision accidents in the future.
本文介绍了计算机模拟方法，以阐明法医专家所面临的问题，即导致两名摩托车受害者（包括摩托车驾驶员和后座乘客）各种损伤特征的原因是什么，以及如何确切确认他们中哪一个是摩托车驾驶员。通过重建两起典型的摩托车与汽车碰撞事故案例，分析了摩托车驾驶员和后座乘客在碰撞过程中的运动和受力情况。在案例一中，后座乘客在被抛到高于摩托车驾驶员并越过汽车顶部后摔倒在地，头部受致命伤。在案例二中，后座乘客右胫骨承受的压力比摩托车驾驶员更大且持续时间更长；后座乘客右胫骨发生爆裂性骨折损伤。这些结果可能对法医专家未来处理类似的摩托车与汽车碰撞事故有所帮助。
