【摘要】 建立基于人体解剖学结构的HBM(Human body model)头部三维有限元模型。详细描述了人体头部的主要解剖学结构,模型由头皮、颅骨、硬脑膜、脑脊液、软脑膜、大脑、小脑、脑室、脑干、脑镰和脑幕等组成。采用人体头部碰撞实验数据,比较了实验与仿真中头部的动力学响应和颅内压力分布参数,对头部有限元模型进行了验证。结果表明,该模型具有较好的生物逼真度,可以用来分析车辆交通事故中颅脑创伤和损伤机制。更多还原

【Abstract】 This study established a finite element (FE) model of human body head (HBM-head) in accordance with human head anatomy. The anatomical structure of HBM-head was described in detail, primarily consisting of scalp, skull, dura mater, cerebrospinal fluid, pia mater, cerebrum, cerebellum, ventricle, brain stem, falx, and tentorium. The kinematic and kinetic responses, as well as the intracranial pressure distribution of the head model were compared with the data from the cadaveric impact tests to validate the head FE model. Experimental results confirmed that the head FE model had good biofidelity and could be used to study head-brain trauma in vehicle collisions and the underlying injury mechanisms.更多还原
