Simulation of Explosive Damage Effect of ATT Warhead on Incoming Torpedo
-
摘要: 为了获得反鱼雷鱼雷(ATT)战斗部水中爆炸对来袭鱼雷的毁伤效应, 以ANSYS LS- DYNA有限元分析软件为平台, 对ATT攻击对象(来袭鱼雷)进行了较为系统的建模, 并采用流固耦合算法针对ATT战斗部在不同距离、不同角度下对来袭鱼雷的爆炸毁伤效应进行了仿真计算, 得出了ATT战斗部的毁伤半径、来袭鱼雷的毁伤判据以及ATT对来袭鱼雷的毁伤规律。仿真结果表明, 在水中爆炸作用下, 来袭鱼雷燃料舱段壳体较其他部分壳体更易发生变形或破裂。该研究可为鱼雷的毁伤效应评定及ATT战斗部研究提供参考。Abstract: To assess the damage effect of anti-torpedo torpedo (ATT) warhead on an incoming torpedo, we establish an incoming torpedo model with the finite element analysis software ANSYS LS-DYNA, simulate the explosive damage effect of ATT warhead on an incoming torpedo with different distances and different angles by using the fluid-solid cou-pling algorithm, and obtain the damage radius of ATT warhead, the damage criterion of an incoming torpedo, and the damage laws of an ATT against an incoming torpedo. Simulation results show that deformation and fracture occur more easily on the shell of fuel tank section of an incoming torpedo than on other shells in underwater explosion. This study may benefit the damage effect assessment of an ATT and the research of ATT warhead.
