| 摘 要： | 空投鱼雷的头部形状不仅影响其在空中和入水后的弹道,而且所受到的入水冲击载荷有很大的差别.为了研究鱼雷头部形状对入水的影响作用,文中利用ANSYS/LS-DYNA数值模拟技术建立了鱼雷入水的有限元模型,并通过对三种不同头部形状的鱼雷入水过程的数值模拟,得到了不同头型的鱼雷垂直入水的压力响应曲线和速度响应曲线,在进行比较分析后讨论了头部形状对入水的影响规律.

| Abstract: | The shape of torpedo warhead affects the trajectory in air and water and impact force.In order to research water-entry effect of different shape of torpedo warhead,a finite element model of torpedo water-entry was built by ANSYS/LS-DYNA numerical simulation.Through numerical simulation of the process of torpedo water-entry with three shapes of torpedo warhead,the pressure response and speed response rule of the torpedo warhead case with different shape of warhead was obtained,and then the rules of the water... |
