摘　　要：建立了基于中国人体特征的50百分位男性头颈部有限元模型,该模型具有详细解剖学结构,尺寸精度较高;基于国外经典的尸体碰撞试验数据,对该头颈部有限元模型进行了有效性验证,并利用该模型模拟了两种典型面部碰撞交通事故案例。结果表明,所建立模型具有较好的生物逼真度,能够正确反映碰撞过程中颅内生物力学响应,可用于研究汽车碰撞事故中头颈部损伤机理及损伤评估等工作。In this research, a 50 th percentile male head-neck finite element model based on the Chinese human body characteristic is constructed, this model has detailed anatomy structure with high dimensional precision; effectiveness of this finite element model is verified based on the classical cadaver crash test data abroad, that simulates two typical frontal crash accident cases. The results show that the head-neck model had a good biofidelity, which can accurately reflect encephalic biomechanical response during vehicle crash, and can be applicable to the research on head- neck injury mechanisms and injury evaluation in vehicle crash accident.
