摘要:
为了研究分层装药结构的内、外层炸药材料、装药厚度对杆式射流成型的影响，利用True Grid和LS-DYNA软件对不同工况下杆式射流的成型进行数值模拟。仿真结果表明:分层装药对杆式射流的影响与内、外层装药的爆速差△D和厚度比d1/d2有关，当d1/d2<4.4时，装药的爆速差△D对射流的增益效果成正相关；当4.48.8时，爆速差△D与射流的增益效果呈负相关。总体上，分层装药结构对射流形态、整体动能和头、尾速度有优化增益作用，且优化和增益效果与内、外层装药的厚度比及材料有关，合理的装药材料以及装药比例能够有效提高杆式射流的毁伤效能。
Abstract:
In order to study the effects of the explosive charge and charge thickness of the stratified charge structure on the jetting projectile charge, the True Grid and LSDYNA software were used to simulate the formation of the jetting projectile charge under different working conditions. The simulation results show that the impact of stratified charge on the jetting projectile charge is related to the difference △D and the thickness ratio d1/d2 between the internal and external charges. When d1/d2<4.4, the velocity difference △D of the charge and its effect on the jet gain positive correlation; when 4.4<d1/d2<8, the stratified charge has no significant effect on the jet; when d1/d2>8.8, the detonation velocity difference △D has a negative correlation with the gain effect of the jet. In general, the stratified charge structure has an optimized gain effect on jet morphology, overall kinetic energy, and head-tail velocity, and the optimization and gain effects are related to the thickness ratio and materials of the inner and outer layer charges, and the reasonable charge materials and charge ratios can be effective to improve the damage performance of jetting projectile charge.
