The Influence of Metal Particles Arrangement of Powder Shaped Charge Liner and its Thermal Treatment on Performance of Jet

利用筛分法,将127型石油射孔弹药型罩中的铜粉进行颗粒分级,并与其他金属粉进行粒度级配,通过粒度分布分析及射孔弹侵彻钢靶试验,研究了粉末药型罩中金属颗粒的粒度级配及分布对聚能射流性能的影响,同时对药型罩进行了热处理研究。结果表明,射孔弹药型罩中铜粉的粒度对聚能射流性能有重要影响,合理的金属粒度级配及分布能提高射孔弹侵彻钢靶的能力。粉末药型罩经热处理后,可提高药型罩的致密性和强度,能有效地改善聚能射流性能。优化后的药型罩使127型石油射孔弹侵彻钢靶深度提高11.6%。

The copper powder of shaped charge liner of the type 127 oil perforation charge was graded by sieving, and the copper powder was arranged properly with the other metal powders. After particle distribution analysis and test of penetration of oil perforation to steel target, the influence of particles arrangement and distribution of powder shaped charge liner on performance of jet was studied and the liner was treated by thermal treatment. The test results show that the particle size of copper powder of shaped charge liner plays a vital part on performance of jet, proper particles arrangement and distribution enhenced the penetration of oil perforation charge to steel target. Thermal treatment on the powder shaped charge liner could increase the density and strength of the liner and improve performance of jet efficiently. The optimized shaped charge liner made the depth of penetration of type 127 oil perforation charge to steel target increase by 11.6%.
