摘要

摘要: 通过对美国MK46鱼雷进行数值仿真, 设置不同的工况, 应用ABAQUS中的声固耦合算法对鱼雷在水下爆炸冲击波作用下的动态响应及其冲击环境进行仿真计算, 分析了鱼雷在不同工况下的毁伤效果, 以及不同部位各节点的加速度响应及冲击环境。有限元计算结果表明: MK46鱼雷首部为薄弱部分, 首部加强筋首先失效破坏, 当壳体冲击因子为1.33时鱼雷壳体发生破损; 迎爆面和背爆面节点加速度响应有较大区别, 通过节点的冲击谱参数可对鱼雷内部设备的抗冲击性能进行分析。本文结果可对相关鱼雷的毁伤效果分析及结构设计提供参考。

Abstract: American MK46 torpedo is numerically simulated in different conditions. The dynamic response and shock environment of MK46 torpedo subjected to underwater explosion is calculated through acoustic coupling algorithm of ABAQUS. The torpedo damage effect is analyzed in different conditions, as well as the acceleration response and the shock environment of each node in different part. Finite element calculation results show that the head of MK46 torpedo is the weak part, and the stiffeners are destroyed firstly. The damage to the torpedo shell occurs when the impact factor is 1.33. There is a clear difference of node acceleration response between the surface facing blast and the surface back to blast, and the impact resistance of the torpedo internal equipment can be analyzed with the spectral parameters of nodes. The study may provide a reference for damage effect analysis and structure design of this kind of torpedoes.
