| Abstract(J) | BEV化による車重増加に伴い従来以上に高い衝突エネルギーを吸収できる構造が求められる．本検討ではODB前突を模擬して軸圧壊と曲げを同時に負荷する条件で，部材重量に対するエネルギー吸収量に優れるハット部材の補強構造を検討した．ハットウェブ面に小型のハット部材を配置する構造がエネルギー吸収効率に優れた． Translation |
| Abstract(E) | Due to the increase in vehicle weight associated with BEV adoption, structures capable of absorbing higher collision energy than before are required. In this study, we examined reinforcement structures for hat-shaped components using crash simulation. Our focus was on designs that provide superior energy absorption performance relative to component weight. The evaluation was conducted under conditions simulating an ODB frontal impact, where axial crushing and bending occur simultaneously. The configuration in which small hat-shaped members are arranged on the hat web surface demonstrated excellent energy absorption efficiency. |
