人车碰撞事故中头盔防护研究

Research on Helmet Protection in Human-Vehicle Collision Accidents

在电动二轮车碰撞事故中,骑行者头部与地面发生的二次碰撞是造成致命伤的重要因素。头盔作为一种道路交通安全的重要防护部件,可有效降低骑行者头部受到的损伤。对人车事故中骑行者头部二次碰撞开展试验,结果表明:车辆撞击速度越快,骑行者跌落高度越高,未佩戴头盔的头型冲击器受到的损伤就越大。佩戴头盔能有效避免骑行者头部受到致命损伤。

In the electric two-wheeler crash accident,the second collision between the cyclist's head and the ground is an important factor causing fatal injury.As an important protective part of road traffic safety,helmet can effectively reduce the head injury of cyclists.A second impact test of the cyclist's head in a human-vehicle accident is carried out.The test results show that the faster the impact speed of the vehicle and the higher the cyclist's fall height,the greater the damage to the head impacter without wearing a helmet.Helmets can effectively protect cyclists from fatal head injuries.
