Fundamental Study on the High-strength Body Structure oriented to the Enhancement of the Ride Down Effect during Vehicular Side Impact

側面衝突におけるライドダウン効果の拡大をめざした高耐力車体の基礎的検討

Present paper describes an approach to the occupants' energy management during a side crash using ride down effect. A benchmark with stiffness of two folds of conventional structure was theoretically proposed. Based on FEM analysis, a body structure consists of CFRP reinforcement was devised. A dummy simulation with the property of devised structure was done, indicating smaller impact speed to the occupant. Based on the FE analysis, a prototype vehicle was built and CTC experiments were conducted using a special MDB with a mass of 10,000kg. The results of the experiments successfully validated the theoretical study and FEM analysis.高エネルギ側面衝突に求められる車体特性の理論検討およびFEM解析から局所車体構造への質量付加による傷害値への寄与(広義のライドダウン効果)を明らかにした.鋼板とCFRPの複合車体構造を構築した.解析をもとに実験車を製作し大型車両との衝突実験をおこない,本研究における検討の妥当性を示した.
