摘要

摘要: 为研究近距爆炸载荷作用下液舱各部分的吸能情况，根据实验建立数值仿真模型，研究在有无液体、不同厚度比和不同水层厚度条件下舱室变形和各部分吸能的占比情况。结果表明，液体介质的存在改变了液舱的吸能模式，液舱总吸能主要受到舱室外壁厚度和水层厚度的影响，厚度比和水层厚度的变化对舱壁变形模式和爆炸能量在液舱各部分的占比有一定影响。对液舱各部分吸能机理的阐述，可作为液舱设计的参考依据。

Abstract: In order to study the energy absorption of different parts of a liquid cabin under a close-range explosion, a fluid-structure coupling model is built on the basis of experiments, and the deformation of the bulkhead and energy absorption ratio of different parts of the liquid cabin are analyzed, in which the influence of the water, bulkhead thickness ratio and water thickness are also discussed. The results show that the existence of a liquid medium can change the energy absorption model of a cabin. The total energy absorption is mainly affected by the front bulkhead thickness and water thickness, and alterations to the bulkhead thickness ratio or water thickness can also affect the deformation model of the bulkhead and energy absorption ratio of different parts of the cabin. A logical explanation of the energy absorption mechanisms of the liquid cabin is proposed, and some useful suggestions for designs are given.
