中文摘要:
      采用泡沫铝填充量(体积分数)为12.15%的泡沫铝-聚氨酯复合材料,在7 800 g的冲击加速度下,建立了3种厚度分别为6,8,12 mm的泡沫铝-聚氨酯的缓冲模型,用Ansys对各缓冲模型进行了应力分析,得到了各模型的变形情况,分析了不同厚度的缓冲模型的冲击吸振性能。结果表明:在一定厚度范围内,厚度越大,泡沫铝-聚氨酯复合结构模型受到冲击时产生的最大应力越大,最大变形量也越大。
英文摘要:
      Aluminum foam-polyurethane composite with 12.15% filling volume of aluminum foam was used as sample. Cushioning models of three different thickness, 6 mm, 8 mm and 12 mm, were established under 7 800 g acceleration. Ansys software was applied for stress analysis of the models and distortion of the models was obtained. The cushioning performance of the models was analyzed. The results showed that the larger thickness, the higher max stress and distortion when the aluminum foam-polyurethane composite material model was impacted within a certain thickness.
