摘要
为探究隔板在小口径聚能装药中的作用,开展了隔板参数与中心通孔药型罩匹配对爆轰产物泄露以及射流侵彻性能的影响规律研究。基于爆轰波正规斜反射理论,推导了药型罩表面不同位置处爆轰波初始入射角和所受压力与隔板参数之间的定量关系式。采用LS-DYNA系统分析了隔板直径和隔板高度对射流成型及侵彻性能的影响。结果表明:在通孔药型罩中添加隔板能有效提高药型罩上的压垮压力,抑制爆轰产物泄漏,提高能量利用率和射流侵彻性能;射流的侵彻能力随隔板直径增大呈先增后减的变化趋势;隔板高度对射流性能的影响呈多极值响应;当隔板直径为6 mm、隔板高度为4 mm时,射流对45钢靶的侵彻深度达到较大值(158.17 mm),较无隔板结构提升了17.21%。研究结果可为小口径聚能战斗部设计提供参考。
To investigate the role of wave shapers in small-caliber shaped charges,the effects of aligning wave shaper parameters with those of center-holed liners on detonation product leakage and jet penetration performance were studied.Based on the regular oblique reflection theory of detonation waves,quantitative relationships between wave shaper parameters and detonation wave initial incident angles/pressure distributions at various positions on the liner surface were derived.Systematic analysis using LS-DYNA software was conducted to reveal the influence patterns of wave shaper diameter and height on jet formation and penetration performance.The results show that adding wave shapers to center-holed liners effectively increases the collapse pressure on the liner,suppresses detonation product leakage,enhances energy utilization efficiency,and improves jet penetration performance.Jet penetration capability initially increases and then decreases with the increasing wave shaper diameter.Wave shaper height exhibits a multi-extremum response effect on jet performance.The largest penetration depth of 158.17 mm into 45 steel targets was achieved with a wave shaper diameter of 6 mm and a height of 4 mm,representing a 17.21%improvement compared to structures without wave shapers.These findings offer valuable insights for designing smallcaliber shaped charge warheads.
