摘要

为研究铝合金蜂窝夹层板水下爆炸冲击波载荷作用的动态响应及抗冲击性能,利用非药式水下爆炸冲击波加载装置对气背固支5A06铝合金夹层板及具有相同面密度的单层板进行水下冲击波加载试验。利用高速相机结合三维数字散斑技术(DIC)对夹层板后面板动态响应进行实时测量,获得夹层板气背面受水下冲击波作用的动态响应历程及变形毁伤模式,比较分析铝合金蜂窝夹层板抗冲击防护性能。结果表明,较相同面密度的单层板,蜂窝夹层板受水下冲击波载荷作用的芯层压缩能有效减少气背面板的塑性变形,提高夹层结构整体抗冲击性能。

Abstract

In the present study, the dynamic response and blast resistant properties of 5A06 aluminium alloy honeycomb core sandwich panels were investigated during impulsive loading in water. Underwater shock loading experiments for clamped aluminum alloy honeycomb core sandwich plates were conducted by the non-explosive underwater explosion shock loading device. Compared with the experimental results of monolithic panels with equivalent area mass, the effects of sandwich panel structures on anti-shock performance were studied by the experiments of underwater shock loading. The dynamic deformation of air back plate of sandwich structure was measured in real-time by the combined technique of high-speed cameras and 3D digital speckle correlation method (DIC). The dynamic response histories and failure modes of clamped air-back sandwich plates were observed to compare the blast resistant properties of aluminium alloy honeycomb plates with monolithic plates. Experimental results show that the blast resistant property of honeycomb structure plates effectively improved by core compressing than monolithic panels with equivalent area mass.
