Within the past decade, injuries caused by electric scooter (e-scooter) crashes have significantly increased. A common cause of fatalities for e-scooter riders is a collision between a car and an e-scooter. To develop a better understanding of the complex injury mechanisms in these collisions, four crashes between an e-scooter and a family car/sedan and a sports utility vehicle were simulated using finite element models. The vehicles impacted the e-scooter at a speed of 30 km/hr in a perpendicular collision, and at 15 degrees towards the vehicle, to simulate a rider being struck by a turning vehicle. The risks of serious injury to the rider were low for the head, brain, and neck, but femur/tibia fractures were observed in all simulations. The primary cause of head and brain injuries was found to be the head-ground impact in cases where such an impact occurred.
在过去十年中,电动滑板车碰撞导致的伤害显著增加。电动滑板车骑手死亡的一个常见原因是汽车与电动滑板车之间的碰撞。为了更好地理解这些碰撞中复杂的伤害机制,使用有限元模型模拟了电动滑板车与家用轿车/轿车和运动型多用途汽车之间的四起碰撞。车辆以30公里/小时的速度垂直碰撞电动滑板车,并以15度角朝向车辆碰撞,以模拟骑手被转弯车辆撞击的情况。骑手头部、大脑和颈部受重伤的风险较低,但在所有模拟中均观察到股骨/胫骨骨折。在发生头部与地面撞击的情况下,发现头部和脑部受伤的主要原因是头部与地面的撞击。
