| 摘 要： | 目前国内外学者日益重视大型储油罐区的安全问题,油罐的防爆炸破坏能力成为研究的热点之一。利用LS-DYNA有限元程序,模拟了油罐钢板在3#岩石炸药爆炸载荷下的破坏过程,分析了炸药质量、药柱形状对钢板破坏程度和破口形状的影响。由于药柱形状规则,钢板主要发生类似冲孔的剪切破坏,破坏程度随炸药质量的增加而加强,爆轰产物会从钢板破口处进入油罐内部。 |

| Abstract: | Presently the domestic and overseas scholars pay more attention to the safety problem of large-scale oilcan section,and the oilcan's explosion resist ability is one of pop research problems.This paper using LS-DYNA finite element analysis program to model the damage process of oilcan steel plate under No.3 rock explosive load,analysing the effect of the mass and shape of explosive to steel plate's extent of damage and shape of crevasse.Because explosive shape is regular,steel plate mainly occurs shear damage similar to hole piercing,the extent of damage gradually increase with explosive mass increasing,finally explosion outcome will enter oilcan's interior from crevasse. |
