| Abstract(J) | 衝突時に変形して衝突エネルギーを吸収する骨格部品について，少量樹脂を超ハイテン部品と薄鋼板製の樹脂固定板で挟んだマルチマテリアル構造を開発した．本構造を980MPa級ハイテン部品に適用すると曲げ圧壊エネルギー吸収量が約45%向上し，同性能の部品と比較して約6%の軽量化を達成，振動特性も向上した． Translation |
| Abstract(E) | A Multi-material structural members for Automobile which absorb the crash energy by deforming in the automotive body collision were developed by sandwiching a small amount of resin between an ultra-high strength steel structural parts and a resin fixing plate made of a thin steel. When this structure was applied to 980MPa grade steel parts, the energy absorption in the bending was improved over 45%, and the weight was reduced by 6% in comparison with the parts of the same performance, and vibration characteristics were improved. |
