| 摘 要： | 为了选择合适的材料和结构作为冲击吸能器以提高舰船设备的抗冲击能力,对冲击吸能器隔冲效果的评估方法进行了研究,提出了隔冲效率、加速度响应不平稳度和压溃率3个评价指标,然后利用LS-DYNA分析软件模拟冲击环境,对泡沫铝、铝管和泡沫铝填充铝管3种材料作为吸能器时的隔冲效果进行了评估比较.研究结果表明,本文提出的评价指标很好地实现了对舰船设备冲击吸能器隔冲效果的有效评估,为冲击吸能器的合理选材和结构设计提供了依据.

| Abstract: | In order to choose the proper material and structure as the energy-absorption to improve the ability of anti-shock protection,the evaluation methods of shock isolation effect of impact energy-absorption of ship equipment are studied,and three evaluation indexes,which are shock isolation efficiency,nonstationarity of acceleration response and deformation rate,are introduced.And then,the shock isolation effects of three energy-absorptions,which are aluminum foam,aluminum tube and aluminum foam-filled tube,are... |
