装甲装备受到弹丸攻击后,要判断内部部件的毁伤情况,采用实弹试验的方法费用高,周期长,安全性差;而采用建模仿真的方法费用低,效率高,安全性好,并且可以为预测装备内部的毁伤部件奠定基础。采用有限元法对破甲弹侵彻均质装甲板进行了数值仿真,对侵彻过程的3个阶段进行了分析,得出了破甲弹射流的动能、平均速度和冲量随时间变化的规律,为侵彻后装甲板内部部件毁伤情况的判断提供了基础数据。
Armored equipment by projectile attack, to determine the damage of internal components, the use of live test method costly, long cycle, poor security; and use of modeling and simulation method of low cost, high efficiency, good security, and can be predicted Equipment inside the damaged parts of the foundation. The finite element method was used to simulate the penetration of armor-piercing projectiles into the homogeneous armor plate. The three stages of the penetration process were analyzed. The kinetic energy, the average velocity and the law of the momentum of the projectile projectile with time were obtained , Which provided the basic data for judging the damage to the internal components of the penetrated armor.
