这项工作的目的是验证一个新的三维人体头部解剖模型，通过模拟一个Nahum的实验，然后复制由摩托车事故造成的头部碰撞的直接头部撞击。在验证水平，模型响应与测量的尸体测试数据进行了比较，在冲击力，头部加速度和五个硬膜外压力。模型反应与Nahum的实验头部反应非常相似。在此基础上，实现了摩托车事故中真实的头部碰撞的数值模拟。该模拟基于交通研究实验室（英国）执行的实验性事故重建。该模拟的结果进行了比较，在这项研究中考虑受伤的摩托车手的医疗观察。在这个摩托车事故的复制，一个很好的相关性被发现之间的数字头部反应，在颅内应力，并观察到脑损伤尸检。
The aim of this work is to validate a new 3D anatomic human head model by simulating a direct head impact of a Nahum's experiment and then to replicate the head impact caused by a motorcycle accident. At the validation level, model responses were compared with the measured cadaver test data in terms of impact force, head acceleration and five epidural pressures. Model response duplicate closely Nahum's experimental head response. After this validation, a numerical replication of a real head impact in motorcycle accident was realized. This simulation was based on the experimental accident reconstruction executed by the Transport Research Laboratory (UK). The results of this simulation were compared to the medical observations for the injured motorcyclist considered in this study. In this motorcycle accident replication, a good correlation was found between numerical head response, in terms of intracranial stress, and observed brain injuries in autopsy.
