Abstract：
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.
摘要：
在过去的十年里，电动滑板车(e-sooter)撞车造成的伤害显著增加。电动踏板车骑手死亡的常见原因是汽车和电动踏板车之间的碰撞。为了更好地理解这些碰撞中复杂的损伤机制，使用有限元模型模拟了电动踏板车与家用轿车/轿车和运动型多功能车之间的四次碰撞。车辆在垂直碰撞中以30公里/小时的速度撞击电动踏板车，朝车辆15度，模拟骑手被转弯车辆撞击。骑手头部严重受伤的风险很低，大脑,脖子,但在所有模拟中均观察到股骨/胫骨骨折.在发生这种撞击的情况下，发现头部和脑部受伤的主要原因是头部地面撞击。
