摘要
通过ANSYS/LS-DYNA有限元分析软件对高速弹体侵彻冰体过程进行数值模拟。研究了正侵彻、斜侵彻及速度变化对弹体侵彻冰体的毁伤效能影响,获得了弹体和冰体在相互作用的过程中的动态响应特性曲线。
The ANSYS/LS-DYNA finite element analysis software was used to simulate the process of high-speed projectile penetrating the ice.The effects of vertical penetration,oblique penetration and velocity variation on the damage efficiency of the projectile through the ice were investigated.Meanwhile,the dynamic response characteristics curve of the projectile and the ice during the interaction were obtained.
