Significantly more fatalities and serious injuries occur due to ejection in roll over accidents. The present study was conducted to determine the occupant retention and head-neck injury potential aspects of laminated glass in side door windows and sunroofs during roll over accidents. The test protocol for this study was based on National Highway Traffic Safety Administration (NHTSA) studies for advanced glazing. The impact study of 18 kg with head-neck form was conducted on laminated glass of side doors and sunroofs from production vehicles. The drop speed was varied from 11 to 16 kph. The Hybrid III 50% male dummy head-neck form was impacted on the approximately center of the glass portion of the windows. The head injury criteria, head resultant acceleration, and neck loads and moments were quantified. A series of drop tests were conducted on roll down side windows with laminated glass. The head-neck biomechanical parameters were well below the critical value injury tolerance limits. Results indicated that the glass contained the dummy assembly and the head-neck biomechanical parameters were below the critical value injury tolerance limits in simulated rollover accidents. The present study demonstrates that head-neck injury is unlikely due to laminated glass side windows and sunroof laminated glass used in production vehicles during rollover accidents and that the dummy is contained by the laminated glazing.
在翻车事故中,因被抛出车外而导致的死亡和重伤人数显著更多。本研究旨在确定翻车事故期间,侧窗玻璃和天窗夹层玻璃对车内乘员的固定作用以及对头部和颈部造成损伤的可能性。本研究的测试方案基于美国国家公路交通安全管理局(NHTSA)对先进玻璃的研究。使用来自量产车辆的侧门和天窗夹层玻璃,对18千克头部 - 颈部模型进行了撞击研究。下落速度在11至16公里/小时之间变化。将Hybrid III 50%男性假人的头部 - 颈部模型撞击在车窗玻璃部分的大致中心位置。对头部损伤标准、头部合成加速度以及颈部载荷和力矩进行了量化。对带有夹层玻璃的电动摇下侧窗进行了一系列跌落测试。头部 - 颈部生物力学参数远低于临界值损伤耐受极限。结果表明,在模拟翻车事故中,玻璃固定住了假人组件,且头部 - 颈部生物力学参数低于临界值损伤耐受极限。本研究表明,在翻车事故期间,量产车辆使用的夹层玻璃侧窗和天窗夹层玻璃不太可能导致头部 - 颈部受伤,并且夹层玻璃能够固定住假人。
