不锈钢面板与铝面板泡沫铝夹芯梁的抗爆性能

为考查泡沫铝夹芯梁的抗爆性能及面板材料对其抗爆性能的影响，采用数值模拟方法分析了面板材料分别为工业纯铝与304号不锈钢，芯材为Alporas泡沫铝共同组成相同质量泡沫铝夹芯梁在不同爆炸荷载作用下的跨中位移与芯材压缩应变的差异。研究结果显示：在爆炸冲量分别为1．82，3．77，6．08，7．0kN·s的作用下，工业纯铝面板泡沫铝夹芯梁跨中位移分别为304号不锈钢面板泡沫铝夹芯梁跨中位移的68％，83％，84％及86％，较304号不锈钢面板泡沫铝夹芯梁具有更好地抵抗爆炸冲击波的能力，面板材料对泡沫铝夹芯梁的压缩应变影响较小。

Anti-blasting Performance of Aluminum Foam Sandwich Beam with Stainless Steel Face Sheet and with Aluminum Face Sheet

In order to study the anti-blasting performance of aluminum foam sandwich beam and its face sheet materials effect factor. The deflection and core compress strain affection of sandwich beam with different material face sheet at varied blasting impulsive are studied by finite element method. The core of sandwich beam is made of Alporas foam and the face sheets are made of aluminum and 304# stainless separately. The results show that the deflection of aluminum face sheet sandwich beam is less that that of stainless steel face sheet sandwich beam. At the anti-blasting performance of sandwich beam impulse, the deflection of aluminum face sheet beam is 68% ,83% ,84% and 86% of the stainless steel face sheet beam deflection. The anti-blasting performance of aluminum face sheet sandwich beam is better that that of stainless steel face sheet sandwich beam. The core compress strain of two type beam is almost at the same level.
