The aims of this study were to compare the responses of human maxilla and frontal bones under 30 degrees-oriented impacts. Maxilla and frontal bones of the same subject were impacted by a guided horizontal steel cylinder. Linear acceleration time histories and force time histories were plotted and corridors were proposed for maxilla bone response. Sensitivity of head dynamics in regard to impact energy level and localization showed the protection of the intracranial contents by the facial bones crushing. Injury risk curves were established for impact on frontal bone, showing a 50% risk injury for impact energy of 265 J or impact force of 7500 N.
本研究的目的是比较人类上颌骨和额骨在30度定向撞击下的反应。同一受试者的上颌骨和额骨受到一个导向水平钢圆柱体的撞击。绘制了线性加速度时间历程和力时间历程,并提出了上颌骨反应的范围。头部动力学对撞击能量水平和定位的敏感性表明,面部骨骼粉碎对颅内内容物起到了保护作用。建立了额骨撞击的损伤风险曲线,显示撞击能量为265 J或撞击力为7500 N时,损伤风险为50%。
