摘要
索膜结构防护门利用钢板的薄膜力与钢丝绳的悬索力来抵抗爆炸荷载的作用,充分发挥了材料的力学性能。设计了一种索膜结构的防护门,并利用有限元软件ABAQUS对其在爆炸荷载作用下的动力响应进行了研究,充分考虑了接触的影响,并通过修改爆炸荷载的压力时程曲线,对各种不同工况下防护门的技术性能进行了评估。
According to the research on the mechanical properties of the cable-membrane structure,the protective door of new cable-membrane structure is designed to play the mechanical performance of the material fully. The dynamic responses of the protective door including the contact influence under the nuclear explosive loads as well as the chemical explosion loads were analyzed. And the performances of the protective door under different conditions were assessed by changing the blast load pressure-time history curves.
