摘　　要：试验验证超高速弹丸连续侵彻靶板时的侵彻效果代价过大,数值模拟预测提供了新的解决途径。建立了超高速弹丸与连续靶板模型,利用ABAQUS软件,结合Mie-Grüneisen状态方程、Johnson-Cook本构方程和Johnson-Cook断裂准则,对钨合金弹丸2km/s初速下连续侵彻钢质靶板进行仿真研究。超高速弹丸可连续侵彻6层厚度为30mm的靶板,相邻靶板受到了弹丸与飞溅单元的共同冲击,最后2块靶板主要受到飞溅单元的冲击。超高速弹丸每穿透一层靶板,头部及弹体表层发生着侵蚀变化、能量损失与速度变化。充塞穿甲是超高速动能弹的典型穿甲形式,穿甲威力大。数值模拟有助于认识超高速弹丸连续侵彻靶板的过程。Firing test is too expensive to prove the effects of hypervelocity projectile continuously penetrating into targets,numeri⁃cal simulation provides one new solution.Models of hypervelocity projectile and eight targets are built.Using ABAQUS,Mie-Grüneisen state equation,Johnson-Cook hardening equation and Johnson-Cook failure criterion,simulation study on continu⁃ous penetration into target of tungsten alloy projectile with 2km/s velocity is done.Hypervelocity projectile can penetrate through six layers of targets with 30mm each,adjacent target is penetrated by flying projectile and spattering elements.The last two tar⁃gets are penetrated by spattering elements mainly.After penetrating every layer of target,its head and surface of projectile under⁃go erosion change,energy lost and velocity lost.Wear armor piercing is the typical style,with more penetration power.Numerical simulation has contribute to know the proceeding of continuous penetration between hypervelocity and targets.
