摘要
针对双层壳体潜艇在鱼雷等水中兵器爆炸作用下壳体的变形及破损问题,采用AUTODYN有限元软件,分析了潜艇典型舱段,在鱼雷接触命中及爆距分别为2、4、6 m条件下,双层壳体潜艇的壳体破口及变形。计算结果表明,潜艇在鱼雷接触命中条件下,耐压及非耐压壳体均出现较大破口,且耐压壳体破口范围更大;在鱼雷2 m爆距条件下,潜艇耐压壳体出现较大破口,非耐压壳体出现较大塑性变形;在鱼雷4、6 m爆距条件下,耐压及非耐压壳体均有较大塑性变形。
The damage and deformation of submarine with double shell, in underwater blasting by underwater weapon such as torpedo, were studied based on AUTODYN. For typical submarine compartment, damage and deformation of the submarine hull in explosionhit contact and with standoff distance of 2, 4, 6 m were analyzed. The results show that the shell appears crevasse damage while torpedo contacts blast, the pressure hull appears crevasse and no - pressure hull presents plastic deformation while distance is 2m from the explosion source, and the pressure hull and no - pressure hull has plastic deformation while distance is 4mand 6m from the explosive.
