聚氨酯泡沫复合夹层板抗爆特性分析

Analysis of Antidetonational Property of Sandwich Panel of Ployurethane Foam

聚氨酯泡沫复合夹层板是一种可广泛应用于防护工程中的新结构形式 ,据此对聚氨酯泡沫材料夹层板进行了爆炸荷载下有限元分析 ,并与粘钢混凝土板及混凝土板两种板结构进行了比较 。

The sandwich panel of polyurethane foam is a new structural form which can be widely used in protective engineering,and finite element analysis is executed for the three different types of panels-the sandwich panel of polyurethane foam,the concrete panel glued with steel sheet and the concrete panel under explosive loadings.The numerical results show that the sandwich panels of polyurethane foam have good property of antidetonation and energy absorption.
