摘　　要：针对轴向侵彻的环形聚能战斗部药型罩内外壁非对称质量的情况,提出了环型药型罩设计的新思路,即内外壁在压跨碰撞点保持等动量原则,建立环形聚能药型罩的质量补偿设计方法.对内外变壁厚和单壁等厚2种类型的环型药型罩进行了设计计算和侵彻实验,分析比较了两种结构药型罩的侵彻效果.结果表明,采用该方法设计的药型罩侵彻效果有明显改善.For an annular shaped charge warhead which penetrates annularly in the axial direction, the annular linear liner is not massively symmetrical in its inner and outer walls of liner, resulting in the deviated annular jet. In this paper a new concept of design is proposed, based on the equivalent momentum of both parts of the liner at its collision point along the axis. A theoretical calculation is presented according to the mass compensation of the liner parts. Designation and penetration test were carried out for the case of dissymmetrical width and one side constant width. The results showed that the improved annular liner shaped charge have an obviously increased penetration depth. This new design method is proved to be reasonable and practical.
