摘要/Abstract

摘要： 通过有限元软件Autodyn模拟了梯度波纹夹层板在空中爆炸载荷下的动态响应，分析了芯层排列顺序对其响应模式和抗爆性能的影响；在此基础上，选择抗爆性能最优的芯层组合填充聚氯乙烯泡沫，研究了填充方式对其抗爆性能的影响；分析了夹层结构的吸能特性。结果表明：芯层壁板厚度从迎爆面到背爆面逐渐减小的组合具有最优的抗爆性能，且只在第一层填充泡沫的梯度波纹夹层板的下面板变形最小；从迎爆面到背爆面单层填充时，聚氯乙烯泡沫的吸能不断下降；随着填充层数增加，下面板变形以及聚氯乙烯泡沫和下面板的吸能逐渐增大。

Abstract: The dynamic response of graded corrugated sandwich plates under air blast loading is investigated using Autodyn software. The effect of core arrangement on the response modes and blast-resistant performances of graded corrugated plates is analyzed. The graded corrugated sandwich plate with a certain core configuration is selected, which is filled with polyvinyl chloride foam. Furthermore, the influence of filling strategy on blast-resistant performances of sandwich structures is studied. The energy absorption property of sandwich structures is discussed. The results reveal that the sandwich plate, of which core web thickness gradually decreases from front face to back face, has the optimal blast-resistant performance. The deflection of bottom face sheet of sandwich plate is minimal, in which the first core layer was filled with foam. As polyvinyl chloride foam is filled into one of the layers of the sandwich plate from front face to back face, the energy absorption proportion of polyvinyl chloride foam continuously declines. The deflection of back face, and the energy absorption of polyvinyl chloride foam and bottom face sheet increase with the increase in the number of filling layers. Key
