研究了反潜潜艇面对水下爆炸的性能状态,特别分析了水雷威胁。水雷的进攻性可产生2种主要效应,第1种是突然释放高压冲击波,第2种是后续产生的气泡破裂效应与潜艇之间的相互作用。利用民用软件LS-Dyna/USA分析了潜艇壳体对水下爆炸的响应。LS-Dyna/USA是一种显式有限元方法软件,其优点是在一次分析中可将两种效应结合在一起。LS-Dyna/USA的结果可与分析软件的结果进行比较,以便验证潜艇对上述两种效应的总响应。值得注意的是,假定壳体是刚性的,可利用能够与REFM(多层海洋和海底的反射和折射)相比较的简化模型软件确定由冲击波引起的潜艇运动学。利用ARIANE,一种DGA/DCE专用软件可确定由气泡脉动激起的潜艇横梁的弹性状态。此外,还讨论了弹性安装设备的运动状态。
The performance status of the submarine submarine in the face of underwater explosion has been studied. In particular, the threat of the mine has been analyzed. Offensive mines can produce two main effects, the first one is the sudden release of high-pressure shock wave, the second is the subsequent bubble rupture effect and submarine interaction. The submarine shell’s response to underwater explosion was analyzed using civilian software LS-Dyna / USA. LS-Dyna / USA is an explicit finite element method software that has the advantage of combining the two effects in one analysis. The results of the LS-Dyna / USA can be compared with those of the analysis software in order to verify the submarine’s overall response to both effects. It is worth noting that the submarine kinematics due to shockwaves can be determined using simplified modeling software that can be compared to the REFM (multi-layer reflection of the ocean and seafloor) compared to assuming the shell is rigid. ARIANE, a dedicated DGA / DCE software, determines the resilience of a submarine beam that is stimulated by bubble pulsations. In addition, the movement of the flexibly mounted equipment is discussed.
