摘　　要：为了研究超聚能射流形成过程中辅助药型罩材料对射流性能的影响,利用AUTODYN-2D软件,采用高精度多物质求解器Euler-2D Multi-material对辅助药型罩材料分别为Wu、Cu、Fe,锥形药型罩材料为Al的截顶辅助药型罩超聚能装药进行模拟。结果表明,与传统聚能装药相比,超聚能装药结构形成的射流性能更优。辅助药型罩材料密度越大,超聚能射流形态和连续性越好;超聚能射流具有更高的头部速度和能量。用Wu、Cu、Fe作辅助药型罩材料时,超聚能射流的最大速度分别为14 400、13 300和13 100m/s,最大能量分别为10.2×10~7、8.5×10~7、7.5×10~7 J/kg,并且材料密度越大,起爆后相同时刻的射流形态越细越长。To study the effect of material of additinal liner on the jet performances in the hypercumulation formation process,the numerical simulation of hyper shaped charge of a trunconical additinal liner,with material of additional liner is Wu,Cu and Fe,respectively and material of conical shaped charge liner is Al,was carried out using AUTODYN-2Dsimulation software and high precision multi material solver Euler-2D Multi-material.The results show that the maximum velocity of hypercumulation of additional liner material as Wu,Cu and Fe are 14 400,13 300 and 13100m/s,respectively,the maximum energy are 10.2×10~7,8.5×10~7 and 7.5×10~7J/kg respectively,and the hypercumulation after detonation becomes slender and longger after the density of the material increases.
