| 摘 要： | 为考察双层球壳结构内爆炸荷载下的动力响应,用ANSYS/LS-DYNA软件进行数值分析研究,得到在不同炸药量(TNT当量)和不同屋面孔洞率情况下,双层球壳结构内爆炸荷载下的动力响应结果。对软件模拟结果分析,随着炸药量的增加,结构最大轴力和最大位移响应值都增加;屋面开孔越大,结构最大轴力和最大位移响应值都减小,有利于结构抗爆。

| Abstract: | To investigate the dynamic response of double - layer spherical reticulated shell under blast load, a numerical simulation mode is estabhshed by em-ploying fluid - structure coupling algorithm ANSYS/LS - DYNA. The analysis results are as follows ： with the increase of amount of explosive, structural maxi-mum axial force and maximum displacement response values increased; and the rate of holes on roof is greater, the maximum axial force structure and the max-imum displacement response values are reduced. So the greater rate of holes on roof is conducive to resistance Blast load. |
