即使在低速到中速的情况下，追尾的机动车撞车事故也与导致头部和颈部受伤的乘员颈部颅骨生物力学密切相关。在本文中，我们提出了一个分析的力学模型，乘员的头部和颈部的运动与建模的目标车辆Delta V在追尾车辆碰撞。随机机械输入变量的加入进一步使模型超越了确定性框架，反映了现实世界撞车和由此造成的伤害的随机性质。这一方法导致了1000个碰撞模拟的特征，量化了Delta V和由此产生的乘员生物力学概率。该模型通过与已发表的86项人体碰撞试验的直接对比进行了验证。总体而言，该模型略微低估了文献中确定的头部峰值加速度的幅度，−为2.6%。该模型的实用性使法医生物力学调查员可以定制一些基本的碰撞输入参数，并适当地探索由此产生的车辆力学及其对损伤生物力学的直接影响。
Even at low to moderate-speeds, rear-end motor vehicle crashes have been strongly associated with occupant cervicocranial biomechanics that lead to head and neck injury. In this paper, we present the development of an analytic mechanics model of occupant head and neck motion as associated with modeled target vehicle Delta V during rear-end vehicular crashes. The inclusion of stochastic mechanical input variables further developed the model beyond the deterministic framework by reflecting aspects of the random nature of real-world crashes and the resulting injuries. This approach led to the characterization of 1000 crash simulations, quantifying Delta V and the resulting probabilistic occupant biomechanics. The model was validated through the direct comparison with 86 published human subject crash tests. Overall, the model slightly underestimated by −2.6% the magnitude of peak head accelerations identified in the literature. The utility of the model allows a forensic biomechanical investigator to customize some of the fundamental input crash parameters and appropriately explore the resulting vehicular mechanics and their direct influence on injury biomechanics.
