钨合金弹侵彻圆柱壳靶板的数值模拟

Numerical Simulation of Penetration for Tungsten-Alloy Projectile Penetrating Cylindrical Shell Target

利用ANSYS/LS-DYNA有限元软件,通过数值计算模拟了反导舰炮系统的钨合金弹侵彻反舰导弹的战斗部壳体的过程,分别计算了钨合金弹以不同的速度侵彻圆柱壳靶板的不同位置时子弹的剩余速度和剩余动能,并对钨合金弹侵彻相同厚度的圆柱壳靶板和平板靶板进行了比较。计算结果表明,子弹的侵彻位置对剩余速度和剩余动能影响很大,钨合金弹侵彻相同厚度的圆柱壳靶板和平板靶板的过程规律相似,只是在数值上有很小的差别。

The process of penetrating anti-ship missile warhead shell target with tungsten-alloy projectile of anti-missile naval gun system was numerically simulated by the finite element code ANSYS/LS-DYNA. The remaining velocity and kinetic energy of the tungsten-alloy projectile were obtained respectively with the different speeds and different penetrating locations, and compared with the results of the flat target pen- etrating with the same projectile. The simulation results show that the location of penetrating has effects on the remaining velocity and kinetic energy of the projectile, and the process of cylindrical shell target penetrating by the same proiectile is similar to the flat target.
