Calculation Method to Determine the Structural Component’s Contribution on the Deceleration of a Passenger Compartment in Vehicle Crashes Based on the Energy-Derivative Method

エネルギー微分による自動車衝突時の客室の 減速度に対する部材寄与度の計算

When optimizing occupant protection, it is important to consider how each structure develops crush forces so that the passenger compartment acceleration can be controlled. In this research, a new Energy-Derivative Method was developed to analyze the acceleration of the passenger compartment using the contributions from the individual structures. In the full-width crash test, the contributions of the crush box and front side member were initially large, on the contrary the contribution of the passenger compartment deformation was large in the final phase. In the ODB test, the contributions of the honeycomb and the passenger compartment were large.衝突時の客室減速度に対する部材の寄与度を定式化し，有限要素法による前面衝突解析で妥当性の検証と，各部材の寄与度を評価した．フルラップ前面衝突では，前半はクラッシュボックスとフロントサイドメンバ，後半は客室変形による寄与が高く，オフセット衝突では，デフォーマブルバリアの寄与度が高いことを示した．
