摘要
为了有效提升隔爆结构衰减爆炸冲击波的性能,解决前级聚能装药结构与后级随进弹的匹配以及隔爆问题,在后级弹头部壳体表面加装隔爆结构,使用有限元分析软件ANSYS/LS-DYNA建立模型,并分别进行了隔爆材料为钢、钢-聚氨酯、钢-铝-聚氨酯、钢-聚脲-聚氨酯-铝和钢-聚脲-铝五种隔爆方式的数值模拟,比较其隔爆能力。数值模拟结果表明:钢板-铝-聚氨酯和钢-聚氨酯复合结构具有较好的吸能性能,适合用做前后级隔爆材料。
In order to effectively improve the performance of explosion shock wave of the explosion proof structure,solve the problem of matching between the structure of the pre stage charge and the problem of flameproof,the explosion structure is installed on the shell surface of the rear warhead,and the model is established by the finite element analysis software ANSYS/LS-DYNA,and the structure of steel,steel-polyurethane,steel-aluminum-polyurethane,steel-polyurea-polyurethane-aluminum and steel-polyurea-aluminum is compared and their flameproof capability is compared.The numerical simulation result shows that the steel-polyurethane,steel-aluminum-polyurethane structures have good energy absorption properties and they are suitable for use as explosion interrupter materials.
