摘要 利用人体脑部的CT图像,建立了一个基于人体解剖学结构的脑部的三维有限元模型。模型生物材料特性分别采用线弹性和粘弹性模型描述。在专业碰撞分析软件PAM-CRASH中,利用建成的颅脑三维有限元模型模拟正面颅脑碰撞过程,得到了碰撞过程的能量、速度、加速度、应力曲线和各个时刻的应力云图,并依据模拟碰撞过程得到的结果进行分析,得出结论。 A human brain 3D finite element model, base on the human brain CT scan image, is proposed, where the material elasticity and viscoelasticity are considered to characterize the material feature. A commercially available software PAM-CRASH is chosen for model analysis, the time history of head acceleration and stress are regaded as model responses. The brain stress contours are also obtained from the impact simulation of the finite element model to draw the conclusions.
