| Abstract(J) | 自動車ボデー骨格に設定された穴が強度に及ぼす影響と穴縁へのフランジ追加による対策を実験的に検討した．穴により稜線部が欠損せず，Karmanの有効幅と同等の平面部を残したとしても最大荷重は低下する．穴縁に短いフランジを設定することにより最大荷重の低下を抑制可能であることを実証した． Translation |
| Abstract(E) | In this study an effect of the hole in the car body structure on the strength and the countermeasures by adding a flange to the hole edge were experimentally examined. The corner is not damaged by the hole, and the maximum load decreases even if a plane surface equivalent to Karman's effective width is left. It was demonstrated that the decrease in maximum load can be suppressed by setting a short flange on the hole edge. In addition, we examined the clarification of the flange shape that achieves both formability and performance using FEM analysis, and confirmed that even a flange with a formable shape has a strength recovery of 100％. |
