摘要:
为实现岩体的高效与精准切割，针对传统聚能射流在环向破岩方面存在的不足，通过数值模拟的方法研究了环形聚能射流应用于破岩的可行性。基于LS-DYNA软件建立炸药-聚能环-空气-靶板多物质耦合模型，并结合实验结果验证了模型的可靠性，进而系统分析聚能环材料、夹角以及装药结构对侵彻性能的影响。研究结果表明：铜质聚能环凭借高密度与良好的延展性，在开孔成形和侵彻作用时间方面表现最佳。聚能环夹角对侵彻效果影响显著，75°夹角时，穿深最大；90°夹角时，开孔宽度最大；但60°夹角时，能够在成孔质量与侵彻深度间实现更优的综合效果。耦合装药下，射流能量集中于轴向做功，有利于增大穿深；而不耦合装药使射流充分拉伸，形成头部速度快、质量小的射流，虽然降低了穿深，但开孔宽度有一定提升。证实了通过优化聚能环材料、夹角以及合理的装药结构设计，可有效改善环形聚能切割器的破岩效果。
