摘要
采用环形多点起爆方式形成聚能杆式侵彻体,运用LS-DYNA仿真软件,研究了壳体厚度对聚能杆式侵彻体速度、长径比等成型参数的影响规律,找出了获得较佳聚能杆式侵彻体的壳体厚度最佳值。结果表明,当壳体厚度与装药直径的比值为0.04～0.06时毁伤元成型比较好,并得到了壳体厚度对毁伤元成型参数的影响规律曲线。同时,采用X光成像试验进行了验证,试验结果与数值模拟结果吻合较好。
This paper adopts annular multi-point initiation mode to form jetting projectile charge, and studies the influence of shell thickness on the formation parameters of multimode penetrator, such as velocity and length-diameter ratio, using LS-DYNA software. The best results of shell thickness to form good jetting projectile charge has been got. When the ratio between shell thickness and charge diameter is from 0.04 to 0.06, the good penetrator can be formed. At the same time, the change curves of the formation parameters of penetrator with the shell thickness are obtained. The simulation results are validated through X-my imaging experimentation, and the experimental data are in agreement with the results of simulation.
