爆炸荷载下张拉膜结构的动力响应研究

Research on dynamic response of tensioned membrane structures under explosion load

利用ABAQUS建立了一种张拉膜结构的有限元模型,模拟了爆炸荷载下张拉膜结构在遭受冲击波作用、弹片作用、冲击波与弹片耦合作用下的一系列动力响应。基于对冲击波-弹片耦合作用下的动力响应研究,通过控制变量分别改变弹片速度和TNT当量,得出了在不同工况下张拉膜结构的动力响应差异。

A finite element model of tensioned membrane structure was established by ABAQUS, and a series of dynamic responses of tensioned membranestructure under blast load were simulated under shock wave action, shrapnelaction, and the coupling effect of shock wave and shrapnel. Based on the study of the dynamic response under the coupling effect of shockwave and shrapnel,the dynamic response difference of the tensioned membrane structure underdifferent working conditions was obtained by changing the velocity of shrapnel and the equivalent of TNT respectively.
