Damage estimation for infant

给出了几个典型的婴幼儿体脑动力学问题的实例。作为这种疾病的典型例子，我们考虑了两种动态输入的情况。其中之一是对坐在儿童限制表(CRS)上的儿童的碰撞影响。为了减小冲击值，研究了采用线束张力主动控制的思想。在计算机模拟的基础上，可以降低伤害的总价值。另一方面，在虚拟人激励试验的基础上，利用精确的有限元头部模型进行仿真，研究了摇晃综合征对婴幼儿脑损伤的影响。在此基础上，明确了预防婴幼儿脑损伤的振动输入临界值。

Some typical example in the dynamic problem of infant body and brain are investigated. As the typical example of this disease, two case of dynamic input is considered. One of them is the crash impact for child sitting on the child restrain sheet(CRS). To decrease the impact value, an idea to use active control of harness tension is investigated. Based on the computer simulation, total value of injury can be reduced. On the other hand, infant brain injury for shaking syndrome is investigated based on excitation test for dummy and simulation using precise FEM head model. Critical value of vibration input is clarified to prevent the infant brain based on this investigation.
