摘要:
建立了一款新型泡沫铝填充多胞圆锥管(aluminum foam?filled multi?cell conical tube,AFMCT)。基于LS?DYNA 软件建立AFMCT 有限元模型,采用准静态压缩实验验证,研究胞元数、锥角、壁厚以及泡沫铝密度等参数对AFMCT 吸能特性的影响规律。结果表明:AFMCT 具有较规整的变形模式,受结构参数的影响不大;壁厚的增大对结构吸能能力的影响最大;胞元数和锥角其次;泡沫铝密度影响最小。研究结果可为薄壁管吸能装置的设计提供参考。
Abstract:
A new type of aluminum foam-filled multi-cell thin-walled cone tube (AFMCT) was established. Firstly, the finite element model of AFMCT was established based on LS-DYNA software, and the quasi-static compression experiment was used to verify it. Furthermore, the effects of cell number, cone angle, wall thickness and aluminum foam density on the energy absorption characteristics of AFMCT were studied by quasi-sta-tic compression experiments. Results show that AFMCT has regular deformation mode, which is not affected by structural parameters. The increase of wall thickness has the greatest impact on the energy absorption capacity of the structure, followed by the cell number and cone angle; the density of aluminum foam has the least impact. The research results can provide reference for the design of thin-walled tube energy absorption device.
