摘要

针对装甲车、舰船等武器装备冲击碰撞防护需求，提出一种气凝胶夹芯冲击吸能结构，采用一级轻气炮系统，结合力传感器、高速摄像及数字图像相关技术，研究10.4 m/s、15.4 m/s、19.0 m/s共3种较高冲击速度下7种气凝胶夹芯结构冲击吸能特性。研究结果表明：随着冲击速度的增加，7种气凝胶夹芯结构的峰值碰撞力、压垮距离、比吸能、平均碰撞力均逐渐增大；相同冲击速度下，随着气凝胶层厚度的增加，气凝胶夹芯结构的比吸能逐渐增大，峰值碰撞力呈下降趋势，碰撞力效率总体变化较小；在研究范围内，较大的气凝胶层厚度有利于结构冲击吸能特性的提高，同时避免过大峰值碰撞力对防护人员或装备的损伤。

Abstract

To meet the impact and collision protection needs of armored vehicles

ships and other weapons and equipment

an impact energy absorption structure with an aerogel core is proposed. Using a one-stage light air gun system

combined with the force sensors

a high-speed camera and digital image related technologies

the impact energy absorption characteristics of seven aerogel sandwich structures at three impact velocities of 10.4 m/s

15.4 m/s and 19.0 m/s are studied. The results show that: the peak impact force

collapse distance

specific energy absorption and mean impact force of the seven aerogel sandwich structures increase gradually with the increase of impact velocity; under the same impact velocity

with the increasing aerogel layer thickness

the specific energy absorption of the sandwich structures gradually increases

the peak impact force decreases

and the overall change of the impact force efficiency is small. Therefore

within the research scope

a larger aerogel layer thickness is beneficial to the improvement of impact energy absorption of the aerogel sandwich structures

and can avoid the damage of excessive peak force to the protection personnel or equipment.

The role of such structures is to absorb the high kinetic energy as strain energy through irreversible deformation of the structure. Many types of energy absorbers were designed for different dynamic high strain rate applications. One of these structures are sandwich structures. The aim of this review paper is to provide a general review on the type of sandwich structures that have been designed as energy absorbers and their performance in crashworthiness and blast related applications. The focus is on the type of core structures being used, namely foam and architected cores. It was found from the review that sandwich structures are viable candidates for such applications not only because of their light weight, but also due to the high-energy absorption capabilities. The work presented in this review paper shows that the data from the literature on this topic are vast and do not converge to any particular sandwich structure design. This presents the potential future research direction in designing sandwich structures, which have wider application at different scales.
