摘要
抗爆门是一种特殊结构,为了真实反映其受力破坏过程并评价其安全标准,应该充分考虑动力效应、弹塑性变形以及门与门框、门轴与轴承之间接触的影响.本文利用动力有限元软件LS-DYNA,对某系列抗爆门的破坏过程进行了动力仿真分析,并充分利用数值分析的优势,通过修改爆炸荷载的压力时程曲线,对各种不同工况下抗爆门的技术性能进行评估.
Blast-resisitant doors are special structures. In order to simulate the damage process and assess the safety of the doors, the dynamic effect, elastic-plastic deformation and contact between the door leaf and the doorframe, the hinges and the bearings should be considered. A certain series of blast-resistant doors are analyzed in this paper with the finite element software of LS-DYNA. With the numerical method, 24 different load curves are analyzed to cover different kinds of loads that the doors may be subjected to.
