通过一系列有效的简化和假设,建立颅脑的三维有限元模型,研究运动着的颅脑撞到静止物上时脑内响应,即颅脑减速损伤.得到了脑区的应力云图,清晰地反应出脑组织内的应力波传播和扩散过程,验证了当头部受到减速撞击时,损伤不仅仅发生在受撞击的局部,且会在应力波的传播方向发生更为严重、更为广泛的对冲性损伤.结果与已有文献及临床医学相符.

Through a series of effective simplification and assumptions,a three-dimensional finite element model of brain is established to study the response of the brain after impacting on a stationary object,and the stress contour is obtained.The results reflect clearly the stress wave propagation and diffusion process and show that the damage occurred not only locally,but more seriously in the direction of propagation of stress wave,which is in agreement with the existing literature and clinical medicine.
