摘　　要：为了低成本的处理爆炸物,提出一种新型的水射流排爆战斗部结构。利用ANSYS/LS-DYNA软件完成了爆炸载荷下不同方案的水束成型的数值模拟,并对优化前后的水束头部速度进行对比分析。研究表明,在装药长径比一定的前提下,当容器锥角为60°、内腔高度为25mm时,水射流头部速度可达4537m/s,可以引爆大多数高能炸药,在爆炸物处理领域有良好的应用前景。此方法对今后的排爆工程有一定借鉴价值。In order to deal with explosive objects on the condition of lower cost,a new structure of warhead which can form water jet was proposed,it was a shape charges by changing the structure and materials based on the conical liner.Using ANSYS / LS-DYNA software to complete numerical simulation of the different options of water jet forming under explosive load.and the velocity of water jet optimized or not was analyzed by contrasting.Research showed that on the premise of the certain length-to-diameter ratio of the explosive charge,when container cone angle was 60 °and cavity height was 25mm,the velocity of forehead of water jet could reach up to 4537m/s,which could be detonated most of high explosive and has a good prospect in the field of EOD.This method has some reference value in the future of the EOD.
