水中弹体在爆炸冲击波作用下的有限元分析

Finite Element Analysis of Missile in Water under Detonation Impact Wave Action

以水中弹体为研究对象,用有限元软件对其在爆炸荷载作用下的瞬态响应进行数值模拟,得出在相同冲击载荷作用下,水中弹体的变形较空气中小,动力(运动)性能较空气中稳定;在爆炸载荷作用下,弹体迎爆面和背爆面受到一样的冲击载荷作用,对背爆面造成的破坏不容忽视等结论。

This article takes missile in water as an object of study.The finite element software is used to carry on the numerical simulation to the missile transient response under detonation load.Some conclusions are drawn： under the same the detonation load,compared with the deformation in air,the missile deformation in water is not obvious and the dynamic performance in water is stable;Under the detonation load,the impact load of the back is the same as the front of missile,and the destruction to the back can not be ignored.
