摘要
为研究串联战斗部前级装药对后级随进战斗部的影响，验证在现有导弹战斗部前端加装环形聚能装药的可行性，利用ANSYS／LS—DYNA软件进行了环形切割器对随进战斗部影响的数值仿真，在不同的前后级距离、不同初始速度条件下，得到了随进战斗部壳体和装药的最大应力值及其所在位置及随进战斗部的速度降。仿真结果表明，随着间距的增大，随进战斗部装药所受的最大压力急剧下降，而两级战斗部间相对速度达到600m／s时，装药将被引爆。研究结果为串联战斗部的隔爆设计提供了依据。
To research the effect of the tandem warhead＇ s front charge on the following warhead and verify the feasi- bility of installing an annular-shaped charge in the front of an active missile＇ s warhead, the annular cutter＇ s influ- ence on the following warhead was simulated by using ANSYS/LS-DYNA software. The max stresses of the follow- ing warhead＇ s shell and charge, their places and the velocity drop of the following warhead were obtained at differ- ent distances between the front charge and the following warhead and at different initial velocities. The simulation results showed that with the distance increasing, the pressure on the following warhead＇ s charge decreased rapidly; when the velocity was 600m/s, the following warhead＇ s charge would be detonated. The results can support the base for the blast-proof design of tandem warheads.
