论文摘要
体育,工作和交通创伤后,脑部受伤是死亡和发病率的主要原因。除了撞击部位的创伤(政变伤害)外,远离冲击位置(非组合)的大脑的其他区域通常也受到影响。我们表明,基于螺钉理论的方法可用于说明造成脑损伤的头部旋转和线性加速度的综合作用。从运动螺钉的内部产物和冲击螺钉获得的标量度量显示为对撞击下非组脑损伤的严重程度和位置的预测指标。这些预测与非人类灵长类动物进行的头部影响实验一致。该方法是使用有限元模拟证明的,并且已经发布了实验结果
Brain injuries are a major reason for mortality and morbidity following trauma in sports, work and traffic. Apart from the trauma at the site of impact (coup injury), other regions of the brain remote from the impact locations (non-coup) are commonly affected. We show that a screw theory-based method can be used to account for the combined effect of head rotational and linear accelerations in causing brain injuries. A scalar measure obtained from the inner product of the motion screw and the impact screw is shown to be a predictor of the severity and the location of non-coup brain injuries under an impact. The predictions are consistent with head impact experiments conducted with non-human primates. The methodology is proved using finite element simulations and already published experimental results
