LS-DYNA程序在战斗部仿真计算中的应用

Application of LS-DYNA Program in Emulation Calculation of Warhead

在简要介绍非线性动力有限元程序LS DYNA及程序中所采用主要算法的基础上 ,着重叙述了它在战斗部仿真计算中的应用 ,并用LS DYNA程序对某型子母弹战斗部火药燃烧驱动子弹的前期运动过程进行了仿真计算 ,获得了子弹的初始运动速度和初始运动姿态以及子弹弹体的初始受力情况。

Based on the non liner dynamic finite element program LS DYNA and its main algorithms, the application of LS DYNA program in warhead emulation calculation is introduced in this paper, and the prior motion process of the bullet driven by the gunpowder combustion of some kind of primary secondary warhead modal is calculated by using LS DYNA program. The initial velocity of bullet scattering of numerical simulation is elementarily according with experimental value.
