摘要
研究了杆式射流对不同角度、不同速度的移动靶板侵彻效果,得出杆式射流对不同条件移动靶侵彻效果的一般规律,为后续实验研究提供了基础。利用Turegrid软件建立战斗部和移动靶板模型,运用ANSYS/LS-DYNA软件进行数值模拟。结果表明:杆式射流对速度范围在0~2Ma的靶板具有良好的侵彻效果,能够形成“通道”,“通道”弯曲程度受到靶板速度和交会角度共同影响;射流侵彻移动靶板过程中,中部和尾部射流对靶板表面开坑、内部扩孔的影响较大;射流的偏移距离受到交会角度和靶板运动速度的共同影响。
The penetration effect of rod jet on moving target plate with different angles and speeds was studied,and the regularity of rod jet penetration effect on moving target with different conditions was obtained,which provided a certain basis for subsequent experimental research.Turegrid software was used to build warhead and moving target plate models,and ANSYS/LS-DYNA software was used for numerical simulation.The results show that the rod jet has a good penetration effect on the target plate with a velocity range of 0~2Ma,and can form a“channel”.The bending degree of the“channel”was influenced by the speed and intersection angle of the target plate.In the process of jet impingement on the target plate,the central and tail jets have great influence on the surface of the target plate and internal reaming.The offset distance of the jet was affected by the intersection angle and the velocity of the target.
