反鱼雷鱼雷毁伤效果计算分析

Investigation into the Damage Effect of Anti-Torpedo Torpedo

水下爆炸冲击下的鱼雷结构动力学响应特性研究和对来袭鱼雷毁伤效果的评定对反鱼雷鱼雷研究具有重要的应用价值。本文以MSC.Dytran有限元计算分析软件为平台,建立了ATT攻击对象的结构有限元计算模型、ATT的炸药模型以及水域模型,并进行了仿真计算,得出了炸药水中爆炸形成的冲击波的传播和作用过程,以及冲击波作用在雷体上的动态响应过程,分析了不同施爆距离、不同水下深度对雷体动态响应的影响。并参考国内外目前普遍应用的舰艇毁伤标准,根据假想模型的仿真计算结果,进行了ATT硬毁伤半径和软毁伤半径的评定,初步得出了ATT对来袭鱼雷的毁伤规律。

It is very important to research the structural dynamic response of torpedo under the shock of underwater explosion and the damage radius of anti-torpedo torpedo （ATT） for the development of ATT. Based on the finite element analysis software MSC. Dytran, models of the torpedo attacked by ATT, ATT explosive, and water area were presented, and simulations were conducted. Therefore, the courses of shock wave propagation and dynamic response on topedo due to blast of ATT＇s explosive were achieved, and the effects of different explosion distances and different water pressures on torpedo were also analyzed. According to the current ship damage standards in the world and the simulation results, damage radii evaluations and different types of damage rules of the torpedo attacked by ATT were obtained.
