为了给装药弹丸设计提供参考,运用ANSYS/LS-DYNA软件对某小口径火炮穿甲爆破弹侵彻钢靶板过程进行仿真,得到了弹丸着角、着速和靶板厚度对装药安定性的影响。结果表明:随着着速增大,装药的安全性越来越差;随着着角增大,装药的安定性先变好再变差,着角为70°和80°时装药安定性不如着角0°时,说明大着角对装药安定性不利;靶板增加到一定厚度时弹丸装药不安全。

In order to provide a reference for design of projectiles, the process of a small caliber artillery armor-piercing high-explosive projectile penetrating homogeneous steel plate was simulated by ANSYS/LS-DYNA. The effect of the projectile angle of attack, velocity and thickness of armor target on safety of charge was obtained. The results indicate that the safety of charge becomes worse with increased impact velocity. The safety of charge becomes better at first and then worse with increased impact angle. The safety of charges is worse when 70 angle or 80 angle than 0 angle. The safety of charge is threated for large impact angle. The projectile charge is not safe when target plate increases to a certain thickness.
