摘要
为了研究不同形状雷头对水雷入水过载及水雷水下弹道的影响,利用流固耦合仿真软件对半球形、锥形、斜锥形、平头半球形水雷击水问题进行数值模拟仿真研究,计算了4种不同雷头形状水雷入水时头部加速度和速度响应随时间的变化。通过研究表明,斜锥形能有效降低水雷入水时受到的载荷,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及其他元器件的抗冲击设计提供有价值参考。
In order to research the influence of the water entry impact acceleration and the underwater ballistic trajectory under the different mine＇s head shape,and the numerical emulation on the mine of different head shape which was semisphere,cone,oblique cone,homalocephalus semisphere was processed,and the water entry variety of acceleration and velocity was calculated.The emulation results show the oblique cone mine was received less impact loading than the others.The emulation results could provide valuable references to the mine＇s configuration design,fuze design,the safety of projectile filling and shock resistance design of other device.
