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,可以用来分析研究车辆交通事故中颅脑创伤和损伤机理。A finite element(FE) model of human body head (HBM-head)was developed in accordance with human head anatomy. The model consists of scalp, skull, dura mater, cerebro-spinal fluid(CSF),pia mater, cerebrum, cerebellum, ventricle,brain stem,falx, tentorium, etc. The cadaveric head impact tests were conducted to validate the head FE model. The kinematic and kinetic responses as well as the intracranial pressure distribution of the head model were compared with experimental data. It is proved that the head FE mod...
