颅脑在加速和减速冲击载荷下的动应力分析

Analysis of Dynamic Stress for Human Skull Brain under Impact Loading with Acceleration and Deceleration

通过测定和研究颅脑在冲击载荷下的动应力变化情况。运用冲击波压力对颅骨各测点产生的频响函数和相干函数 ,对脑损伤以生物力学的观点作了进一步的研究 ,得到了一些临床医学无法得到的数据。

In this paper, we measure and analyze the changes of dynamic stress in human skull brain under impact loading. By applying the frequency responding function and coherence function produced by the pressure of impact wave at each point on skull, and by use of the viewpoint of biomechanics, we further research into brain injuries and have got some data which cannot be obtained in clinical setting.
