内容記述 |
The purpose of this study is to examine the effect of head rotational motion on brain shear strain. A head physical model constructed from individual medical images of a head was used for the experiments. The model consists of the parts reconstructing the skull, falx, cerebrospinal fluid (CSF) and brain, which represents actual human head shape. Rotational impacts were applied around frontal axis of the model under the conditions in the case that maximum angular acceleration and angular velocity were controlled. As the results of experiments, shear strain in brain part correlates strongly with peak change of angular velocity but correlates poorly with maximum angular acceleration which has been often proposed as a head injury criterion. The reason is that brain shear strain is relatively small at the time when angular acceleration reaches the peak value because relative motion of skull and brain occurs due to the structure of the head consisting brain, falx, skull and CSF. Thus, peak change of angular velocity of a head should be included in the injury criterion in the case that rotational motion of a head occurs. |
