摘要
应用Autodyn有限元计算程序,建立潜艇典型舱段在1 000 kg TNT当量装药水下爆炸,潜艇壳体距爆炸中心30 m,60 m,120 m,180 m四种工况条件下的潜艇壳体损伤及潜艇典型位置冲击环境。计算结果表明,远场爆炸条件下,潜艇壳体迎爆面一般不会出现塑性损伤,潜艇舱室隔板是应力最大的部位。30 m,60 m,120 m,180 m四种工况条件下,潜艇典型位置的速度响应峰值分别为6.5 m/s,4.5 m/s,1.6 m/s和1.0 m/s。
Non-contact explosion can damage the submarine shell and can damage the equipments also. The 1000 kg TNT explosive underwater explosion load to typical submarine cabin has been calculated based on autodyne with four cases while distance is 30 m,60 m,120 m and 180 m from explosion source.The results show that the maximal plastic deformation occuredin the clapboard,not in the center rib of surface face explosion. The peak value of velocity response is 6. 5 m / s,4. 5m / s,1. 6 m / s and 1. 0m / s with different cases.
