中文摘要: 基于磁爆加载下强磁体形成磁场的理论,通过分析高频磁场和低频磁场对聚能射流不同的增强作用机理,对强磁场条件下聚能射流延缓断裂的磁流体动力学原理进行研究。通过理论分析、数值计算和试验研究相结合的方法,研究强磁场与聚能射流的耦合作用特性,分析强磁场对射流稳定性的影响及作用规律,并通过X-光试验分析强磁场作用下射流断裂时间的变化,通过DOP试验分析强磁场对聚能射流侵彻能力的增强效应。强磁场与聚能射流的耦合特性研究为提高聚能装药战斗部毁伤能力、实现高效毁伤提供理论支持。强磁场与聚能射流的耦合技术是新型高效破甲理论的一个重要研究方向,强磁场耦合聚能射流特性研究的突破将为我国今后研制新型高效毁伤弹药提供强有力的技术支撑,可实现破甲战斗部技术跨越式发展。

英文摘要: Based on the theoretical of high magnetic field powered by flux compression generator (FCG), this project will study the magnetohydrodynamics(MHD) principle of shaped charge jet be delayed fracture through strong magnetic field by analyzing the enhancement effect of low frequency magnetic field and high frequency magnetic field for shaped charge jet. They will be studied that mechanism of the strong magnetic filed coupling with the shaped charge jet and the effect of strong magnetic filed for the stability of shaped charge jet by theory analysis, expermental reasearch and numerical simulation. The change of the shaped charge jet fracture time will be evaluated throug X-ray experiments and the enhancement effect of strong magnetic fields will be proved by DOP experiments. The study can prove a reference and theory support for the shaped charge warhead design and efficient damage theory, and the shaped charge warhead technology will promote crossover development.
