摘要
对模拟的头-颈系统施加轴向摆锤冲击,测量充液球壳的载荷和压力响应,证实了颅脑空化所必须的负压条件,研究了液内负压同撞击载荷及颈约束的关系.文中还讨论了实验结果对颅脑空化损伤的意义.
A model of the head neck system was loaded by axial impactwith a pendulum.The load response of the water-filled spherical shell andits dynamic pressure response in water were measured.The negative pressurecondition necessary for braining cavitation was verified.The relation of thenegative pressure to the impact load and neck was also studied.The impli-cation of investigation results for brain cavitation injury is finally discussed.
