摘要
通过粘钢实现一典型汽车库人防口部封堵的设计方案,并用有限元分析软件对其进行三维有限元动力数值分析。对原设计方案进行相似设计后,对粘钢接头结构试验模型在核爆炸压力模拟器中进行模爆试验,得到沿竖向支座钢板的位移和应变时程曲线,并和有限元数值解进行了对比,其结果均较吻合;验证了粘钢接头结构在6级人防爆炸冲击波下可安全使用,由此论证了这类技术用于平战功能转换的可能性和优越性。研究成果不仅具有学术价值,而且有应用前景。
By similar design to the joint structure of bonded steel plate to carry out an on - site test in the nuclear blast pressure imitation container, the three dimensional FEM is adopted to a gateway of civil defense structure of a typical garage closed up by steel plates, obtaining the displacement and strain to move in response to the timing of nodes of vertical abutment steel plate, and the numerical results agree with the analytical results with reasonable reliability. It is proved that the joint structure of bonded steel plate can be safely used, in case of suffering from grade 6 civil air defensive blast shock wave. In the meantime, this method is proved to be possible and optimal for functional transformation from peacetime to wartime.
