摘要

空穴结构可以对其后方区域进行有效防护

为研究空穴结构对泡沫铝夹芯板结构能量衰减性能的影响

通过改变泡沫铝芯层空穴的直径以及厚度

探究浅埋炸药爆炸加载实验条件下空穴尺寸对夹芯板挠度、板后次生冲击波以及泡沫铝芯层吸能效率的影响。研究结果表明:随着泡沫铝中空穴厚度的增加

结构后方的次生冲击波强度显著降低

当空穴直径为0.3

(

为自由面直径)、厚度为1/3

(

为泡沫铝板厚度)时中心压力强度最低

约为无孔泡沫铝板的63%;在直径为0.3

、厚度为2/3

情况下泡沫铝芯层的总变形量最大

相比对照组提升61%;空穴结构可以有效增强泡沫铝夹芯板结构的吸能性能。

Abstract

The cavity structure can effectively protect the rear area. In order to study the influence of the cavity structure on the energy attenuation performance of aluminum foam sandwich plate structure

the influence of the cavity size on the deflection of sandwich plate

the secondary shock wave behind the plate and the energy absorption efficiency of aluminum foam core layer under the experimental conditions of explosion loading of shallow-buried explosive is investigated by changing the diamet

er and thickness of the cavity in the aluminum foam core layer. The results show that the intensity of secondary shock wave behind the structure decreases significantly with the increase of the cavity thickness in the aluminum foam. When the cavity diameter is 0.3

and its thickness is 1/3

the central pressure intensity is the lowest

which is about 63% of that of the non-porous aluminum foam plate. The volume strain is the largest when the cavity diameter is 0.3

and its thickness ias 2/3

which is 61% higher than that of the control group. The surface cavity structure can effectively enhance the energy absorption efficiency of aluminum foam sandwich structure.

The purpose of this paper is to propose a concept that involves the use of side-vent-channels attached to the V-shaped vehicle underbody. Since the solution does not connect the bottom and the roof or pass through the cabin of a light tactical vehicle, this solution is not expected to: first, reduce the available cabin space; second, interfere with the vehicle occupants’ ability to scout the surroundings; and third, compromise the vehicle’s off-road structural durability/reliability. Furthermore, the concept solution attempts to exploit ideas and principles of operation of the so-called “pulse detonation” rocket engines in order to create a downward thrust on the targeted vehicle.
