| 摘 要： | 运用理论分析和数值模拟的方法,对带有药型罩的多点同步起爆、多点分时起爆两种起爆方式进行了比较研究,并使用ANSYS/LS-DYNA对不同的起爆方式所产生的爆轰波形、压力云图和速度历程进行了仿真验证。仿真实验结果表明,只要精确控制起爆时间,多点分时起爆具有更佳的聚能效应。对战斗部起爆方式的设计具有工程实用价值。

| Abstract: | By theoretical analysis and numerical simulation, the effects of multi-point simultaneous initiation, multi- point timesharing initiation with charge liner were conparatively studied. The ANSYS/LS-DYNA is applied to simulate the detonation wave front, pressure field and velocity history of different initiation modes. The results of simulation experi- ment show that multi-point timesharing initiation can be more shape charge effective as long as the initiating-time is controlled precisely. The paper has practical value in designing of initation modes of warhead. |
