随着恐怖袭击事件的愈演愈烈,一些大型民用建筑和工业建筑已经成为恐怖分子的主要袭击目标。以往的爆炸研究主要集中在军事工程方面,在进行大型民用建筑和工业建筑设计时,对于建筑物的抗爆性能考虑很少。而抗爆门作为人防工程、军事工程中的重要部件,是人员、设备进出的重要通道,对保护室内人员安全起到重要作用。我国的抗爆研究起步较晚,关于抗爆门设计方面的规范较少。因此,抗爆门的研究是有很大实用价值的。本文利用有限元软件ANSYS/LS-DYNA,对平板抗爆门在爆炸冲击荷载作用下的动力响应进行分析,以对其抗爆性能进行评估,为抗爆门设计提供依据。
As the terrorist attacks intensified, some large-scale civilian buildings and industrial buildings have become the major targets of terrorists. Previous studies of explosions focused mainly on military engineering. In the design of large-scale civil and industrial buildings, there was little consideration for antiknock performance of buildings. The anti-explosion door as a civil air defense engineering, military engineering is an important component of personnel, equipment access to an important channel for the protection of indoor safety plays an important role. China’s antiknock study started late, on the blast door design specifications less. Therefore, the study of anti-explosion door is of great practical value. In this paper, the finite element software ANSYS / LS-DYNA is used to analyze the dynamic response of the flat explosion-proof door under the impact load of explosion to evaluate the antiknock performance of the anti-explosion door.
