Investigation on Generational Difference of Intracranial Responses Using Age-specific Human Head/Brain FE Models

年代別人体頭部有限要素モデルを用いた 加齢による脳内応答の変化に関する研究

High frequency of fatal head injuries of the elderly is one of the important issues in traffic accidents in Japan. While a human head/brain FE model is a useful tool to investigate head injury mechanism, there has not been a research result using a model considering the structural and qualitative changes of the brain by aging. In this research, to get the basic knowledge to consider a new injury criterion for brain injury of the elderly, the generational difference of intracranial responses related to traumatic brain injuries (TBI) under impact loading was clarified using age-specific human head/brain FE models.国内の交通事故による死者低減のためには,高齢者の脳傷害基準作成が重要な課題の一つであるが,ほとんど研究がなされていない.本論文では,形状及び物性の年代差を反映した頭部有限要素モデルを用いて同一衝撃条件における脳内応答の変化について調べ,高齢者の傷害の受けやすさに影響する要因について検討した.
