摘要
测试鱼雷聚能战斗部爆炸成型弹丸(EFP)对潜艇结构的毁伤效果,考核战斗部威力指标,有利于准确评估反潜鱼雷聚能战斗部毁伤威力。利用有限元分析软件ANSYS/LS-DYNA,采用ALE流-固耦合算法,分析了EFP在侵彻过程中速度和加速度的变化规律,计算出装药量1.882 kg缩比鱼雷聚能战斗部EFP穿透厚度650 mm潜艇模拟水舱后,对潜艇耐压舱模拟靶板的侵彻破孔直径为49 mm,EFP穿透6层间隔后效靶之后,余速131.5 m/s。与实验结果对比,两者结果比较接近,表明模型建立合理,数值模拟算法选择正确,可为评估鱼雷战斗部毁伤威力提供参考。
The test of damage effect of the explosively-formed projectile （EFP） on submarine structure is of benefit to evaluate the damage power of anti-submarine torpedo shaped charge warhead. The varing law of the velocity and the acceleration of EFP during penetration processes are analyzed, and the damage effects of the stimulant targets of submarine structure are calculated by finite element analysis software ANSYS/LS-DYNA with ALE fluid-structure coupling algorithm. The EFP of 1. 882 kg explosive warhead causes 49 mm crevasse on the simulant target of submarine pressure cabin after penetrating 650 mm simulant water cabin, and its still keeps the velocity of 131.5 m/s after penetrating 6 additional steel shells. Simulation results show that the model is reasonable, the algorithm is correct, and the damage effects are close to the experimental ones.
