着速和着角对水雷入水过载影响的数值仿真分析

为了研究高速水雷入水时受到的过载情况,采用流固耦合仿真软件MSC-Dytran,对水雷击水问题进行数值模拟仿真研究。分别计算了不同入水情况下雷体指定部位的加速度响应随时间的变化。仿真结果表明水,雷冲击载荷随入水速度的增大而迅速增大,入水速度是水雷受到的冲击载荷大小的主要影响因素。对新型水雷的结构设计、引信的设计、水雷装药的安全性设计以及其他元器件的抗冲击设计提供有价值参考。

Research on numerical simulation of mine water-entry impact acceleration under different impact velocity and angle

For reseaching on mine water-entry impact acceleration under high impact velocity,the numerical simulation experiment of mine water entry was proposed by using famous numerical emulation software MSC-Dytran.Calculate separately acceleration response follows from the change of time at different condition of water entry. The result indicate that the impact velocity effect the mine water-entry impact acceleration clearly. The emulation data provides reference for torpedo design include structure design, fuse d...
