摘要

为促进无伞空投技术的发展,重点研究复合结构体无伞空投箱的冲击特性,分析无伞空投箱的冲击响应和失效破坏形式。首先从理论角度分析无伞空投箱的防护机理,然后建立典型包装箱模型,利用有限元法进行深入仿真分析。仿真结果表明,棱跌落和角跌落的物资向下位移大,箱体变形严重,冲击持续时间长;无伞空投箱的冲击能量吸收率均大于80%,高效的能量吸收为物资安全性提供了有力保障;与棱跌落和角跌落相比,面跌落物资的加速度峰值和平均冲击力更大;棱跌落和角跌落,无伞空投箱的应力应变水平更高,面跌落的应力应变水平更低。研究表明,物资的安全性与物资的冲击面积、泡沫冲击厚度有关,较小的冲击面积和较大的泡沫厚度可以降低物资损坏风险;无伞空投箱的失效破坏与其冲击面积相关,较大的冲击面积可以有效降低冲击失效程度,提升物资的安全性。

Abstract

To promote the development of parachute-free airdrop technology, the impact characteristics of parachute-free airdrop box with composite structure were studied, and the impact response and failure modes were analyzed. Theoretically analyzing the protection mechanism of the parachute-free airdrop box, followed by in-depth simulation using finite element method. The simulation results show that the goods with edge drop and angle drop have large displacement, serious box deformation and long impact duration; the impact energy absorption rate of parachute-free airdrop box is more than 80%, and the efficient energy absorption provides a strong guarantee for goods safety; compared with edge drop and angle drop, the peak acceleration and average impact force of goods are larger for face drop; when the edge drop and the angle drop, the stress and strain level of the parachute-free airdrop box is higher than the face drop. The study shows that the safety of goods is related to the impact area and foam impact thickness, smaller impact area and larger foam thickness can reduce the risk of goods damage; the failure of parachute-free airdrop box is related to their impact area, larger impact area can effectively reduce the degree of impact failure and improve the safety of goods.
