钨合金块提高小口径火炮穿甲爆破弹穿甲威力仿真

Simulation of Improving Penetration Power for Small Caliber APHE Projectile with Tungsten Alloy Block

为了提高小口径火炮穿甲爆破弹的穿甲威力,提出在弹体头部增设钨合金穿甲块结构;运用ANSYS/LS-DYNA软件对头部增加钨合金穿甲块前后的两种弹丸以不同着角、不同着速侵彻不同厚度均质钢靶板过程进行仿真,得到了弹丸穿靶过程中的动能、速度变化规律以及穿靶后弹丸的剩余动能;在弹体头部增设钨合金穿甲块,有利于增强弹丸的穿甲性能,在弹丸质量不变的前提下穿甲厚度可增大20%左右,在侵彻较厚靶板时效果更为明显。

In order to improve penetration power of small caliber artillery armor--piercing high--explosive projectile, add tungsten alloy penetrating block in the projectile body head was presented. The process of the two kinds of projectile adding or not tungsten alloy penetrating block in the head penetrating different thickness of homogeneous steel target plate with different impact angles and different impact veloci- ty was simulation by ANSYS/LS--DYNA. Rule of kinetic energy and velocity in the process of penetration target plate, after penetration target plate residual kinetic energy was obtained. Add tungsten alloy penetrating block in the projectile body head can increase projectile pene- tration capability. The penetrating thickness can be increased about 20% when projectile mass unchanged and the effect is more obvious when penetrating thickness become thicker.
