摘 要:利用ANSYS-LS/DYNA 3D有限元软件对弹体侵彻混凝土靶板进行三维数值模拟,得到了靶内弹道破坏特征及弹体运动轨迹,并分析侵彻速度和加速度与时间之间的关系,与试验结果比较,该现象与仿真结果基本一致。结果表明:有限元软件能较好的演示混凝土的破坏过程,揭示试验中无法观察到的现象,预估斜侵彻弹体的侵彻深度及方向偏转。Projectile penetration into concrete target was simulated by finite element software ANSYS-LS/DYNA 3D.Penetration trajectory and the failure characteristics of projectile penetration into concrete material were gained.The calculation result was in good agreement with the experimental data.The results show that the failure process of concrete can be well demonstrated by finite element code.The phenomena can't be observed in the test are revealed.Penetration depth and deflection of the penetrating missile body were estimated.
