摘要

为研究舰船双层底部结构在水下爆炸载荷下的毁伤特性，进行电火花气泡与带破口双层结构模型相互作用实验，使用高速摄影机捕捉气泡在带破口双层结构下方的脉动特征，并使用LS-DYNA软件对该实验工况进行模拟，通过实验验证数值模型的有效性。在此基础上建立实尺度舰船双层底舱段有限元模型，通过改变爆距和双层板间水位，设置15个模拟工况，深入分析冲击波和气泡载荷对舰船双层底部结构的毁伤特性。研究结果表明：爆距较小时，外底板出现破口，内外底板之间的内气泡的膨胀作用加剧外底板破口的撕裂，同时使内底板出现塑性变形；爆距较大时，外底板仅发生变形，并与内底板接触，同时带动内底板的变形。双层板间水位较低时，冲击波载荷衰减较大，对内底板毁伤作用较小，此时内气泡的膨胀对内底板的变形起到主要作用；双层板间水位较高时，冲击波载荷衰减较小，冲击波和气泡脉动二次压力波载荷通过水介质共同作用到内底板，使内底板产生变形。

Abstract

To study the damage characteristics of a ship’s double bottom structure subjected to underwater explosion. Experiments on the interaction between the electric spark bubble and the ship’s double bottom structure with a hole are carried out. The pulsation characteristics of the bubble are captured by a high-speed camera

and the experiment is simulated by LS-DYNA to verify the effectiveness of the numerical model. Then

the finite element model of the full-scale cabin is established. By changing the explosion distance and water level between the double bottoms and designing 15 simulation scenarios

the damage characteristics of the double bottom structure subjected to shock wave and bubble loads are analyzed. The results show that: when the explosion distance is small

the outer bottom is broken

and the expansion of the "inner bubble" intensifies the tearing of the outer bottom and causes the plastic deformation of the inner bottom; when the explosion distance is large

the outer bottom only deforms and contacts with the inner bottom

driving the deformation of the inner bottom at the same time; when the water level between the two bottoms is low

the shock wave load attenuation is large with a small damage to the inner bottom

and the expansion of the "inner bubble" plays a major role in the deformation of the inner bottom; when the water level between the two bottoms is high

the shock wave load attenuation is small

the shock wave and bubble pulsation loads propagate through the water medium and act on the inner bottom

whose combined action causes its deformation.

The calculated results of explosion load under near-free liquid surface boundary conditions were compared with the calculated results of empirical formulas in Ref.［6］ and the experimental results in Ref.［17］, verifying that the proposed numerical simulation method can well reflect the shock wave pressure of the near-field underwater explosion and the multiple bubble pulsation processes. The technology is used to build a numerical simulation model close to the actual combat boundary conditions, and calculate and analyze the damage mode of the torpedo near-field explosion to the ship under multiple conditions. The results show that different boundary conditions in the near field have an important effect on the pulsating load of underwater explosion bubbles. Under different conditions, shock wave, bubble pulsation and water jet load have complex coupling effects with ship structure. The effect of torpedo on the ship in the near field under different conditions shows different energy output structures, which is closely related to the final damage mode of ship, and there is an optimal detonation distance to maximize the total energy of torpedo acting on the ship.

The loading type of the double bottom tanks during semi-load and full load conditions was analyzed, and the influence of explosive distance and loading condition on the loading characteristics of internal plate was discussed. The result showed that the transmitted shock wave is the major threat of the inner plate in full-load condition; the splashing loading is the major threat of the inner plate in semi-load and non-contact situation; and high-velocity water-jet is the major threat of the inner plate in semi-load and contact situation. Therefore, the semi-load condition of double bottom tanks is strongly recommended to warship in active time.
