A Simple Dynamic Model Based on Human FE Model in Side Impact Crash

人体FE モデルに基づく側面衝突時の簡易人体力学モデルの構築

A simple dynamic human model in side impact crash is introduced based on finite element (FE) model. The simple dynamic model consists of three masses corresponding to the thorax, the upper body and the lower body. The thorax mass was introduced in order to consider the thoracic deflection. The thorax and the upper body were connected by a linear spring and a linear damper in parallel. Numerical simulations show that the simple dynamic model can approximate the thoracic deflection, the upper body displacement, and the lower body displacement of the human FE model in side impact crash.人体の特性を再現した詳細な人体FE モデルを用いた側面衝突シミュレーションに基づき,車両衝突時の乗員保護方法を検討するために有用な簡易人体力学モデルを構築する.胸部変形量や人体の移動量などの応答結果を比較し,構築した簡易モデルと人体FE モデルとの整合性について検証する.
