  • 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.
