Abstract: Based on the finite element numerical simulation method, the damage simulation of a certain type of armored equipment was studied. The numerical simulation model of ammo power was established. Based on 3D modeling technology, the vulnerability model of the armored equipment in the component level with high-resolution was established. The spatial relation model of projectile and target was established based on the interaction analysis of projectile and target. According to the characteristic of ammo damage element, combined with the damage criterion of armored equipment component, the damage condition of the component and the damage grade of the armored equipment were determined. Meanwhile, the simulation system of armored equipment battle damage assessment was constructed, and the damage simulation analysis of a certain type of armored equipment was carried out, which was foundation for further research on the damage of armored equipment.

Key words: finite element analysis, armored equipment, damage, simulation
