为分析杆式射流起爆点误差对移动斜靶的侵彻,利用ANSYS/LS-DYNA软件建立不同起爆点的战斗部模型,并分别进行数值模拟。结果表明:随着起爆点的偏移,其着靶前射流的偏移量增加;着靶速度降低,负方向对应的着靶速度优于正方向;对靶板的作用时间也增加,负方向对应的作用时间长于正方向;穿透靶板的体积也增加,负方向对应的靶的透孔体积大于正方向。起爆点偏离中心轴距离越大,则毁伤效果越差。
In order to analyze the penetrating error of rod jet penetration on moving inclined target, a warhead model with different initiation points was established by ANSYS / LS-DYNA software, and the numerical simulation was carried out respectively. The results show that the offset of the jet before the target increases with the offset of the detonation point, the target velocity decreases, the target velocity in the negative direction is better than the positive direction, the target time is also increased, and the negative direction The corresponding action time is longer than the positive direction; the volume that penetrates the target plate also increases, and the volume of the through hole corresponding to the negative direction is larger than the positive direction. Detonation point away from the center axis the greater the damage, the worse.
