摘    要:采用ALE方法对射孔弹射流形成的过程及聚能射流对混凝土靶板的侵彻进行了数值模拟,对比了锥形药型罩的不同锥角对聚能射流形成和侵彻的影响.研究结果表明药型罩的锥角大小对聚能射流的速度和形状、射流头部和杵体的质量、侵彻的宽度和深度有着明显显著的影响.小锥角射流头部比重较小且杵体速度未达到侵彻临界值而无法起到很好的侵彻效果,大...

关 键 词:ALE方法  油井射孔  侵彻  药型罩锥角  聚能射流

Abstract:ALE methods were used to simulate the forming process of the shaped charge jet for perforating bullet and the penetration of the jet on concrete plate.Different cone angles were compared to study the effects on the formation and penetration of the shaped charge jet.Results indicated that cone angle plays a key role on the velocities and the shapes of the jet,the quality of jet head and pestle body and the penetration of width and depth. For smaller cone angle,the penetration is not good enough because the j...
Keywords:ALE method  oil well perforation  penetration  liner cone angle  the shaped charge jet
