摘要
夹芯板结构由于能够有效衰减爆炸荷载在爆炸防护领域得到了广泛的应用,采用三维编织法制备的编织结构夹芯板在建筑物墙板制造和爆炸防护方面有较好的应用前景。为此,综合目前钢丝编织结构夹芯板的工艺特点,提出了由三角螺旋式高强钢丝编织的新型“类金字塔”型编织结构夹芯板,并开展了高强钢丝编织结构夹芯板力学特性的理论分析和抗爆试验。研究结果表明:1)提出的“类金字塔”型编织结构夹芯板具有相对密度低、等效抗压强度高、制备工艺简单等优点;2)在爆炸荷载作用下,“类金字塔”型编织结构夹芯板表现出了优异的抗爆防护性能;3)“类金字塔”型编织结构夹芯板中芯层高度对其抗爆性能有影响,芯层高度为78mm的夹芯板抗爆性能优于芯层高度为68mm的夹芯板。
Due to high specific strength,high specific stiffness,and good vibration reduction and energy absorption effects,lattice structural materials are widely used in the field of anti-blast.However,from the aspects of preparation process,blast resis⁃tance and economy,the application of the lattice material sandwich panels which used in the field of ships and armor now is difficult in the field of building explosion protection for large-scale.Therefore,the process characteristics of the current steel wire woven lat⁃tice structural sandwich plate are taken into account,and a new"Pyramid-like"lattice structural materials with triangular spiral high strength steel wire weaving is proposed.The theoretical analysis and blast test of mechanical characteristics of lattice sandwich plate are carried out.The results show that,firstly,"Pyramid-like"lattice material sandwich plate has the advantages of low rela⁃tive density,high equivalent compressive strength,and simple preparation process.Secondly,compared with solid steel plates,when the mass per unit area is constant,the"Pyramid-like"lattice sandwich plate has better blast resistance.Lastly,the height of the core layer of"Pyramid-like"lattice material sandwich plate has an effect on blast resistance.With the increase of the height of the core layer,the anti-blast energy absorption effect is better.
