摘要: 采用脉冲X光照相及威力效应实验，对两种大锥角药型罩装药结构侵彻体的形成及它们对混凝土的侵彻能力进行了研究，获得了两种大锥角药型罩装药结构形成侵彻体的形状、头尾速度及它们对混凝土靶的侵彻参量，对比了半无限厚混凝土靶板及多层有限厚薄靶板对侵彻威力的影响。结果表明，在小炸高条件下，两种大锥角药型罩装药结构能够形成较理想的爆炸成型杆式侵彻体，在混凝土靶中形成孔深与孔径兼顾的孔道。

Abstract: The characteristic of shaped charge with jetting projectiles formed by two types of liner structure and their penetration capability to concrete were studied by X-ray flash radiographs and penetration effect test. The penetration parameters of different charges were measured and compared for semi-infinite and multi-layer concrete targets respectively. Results show that two types of liner structure can form ideal shaped charge with jetting projectile and generate penetration holes with both reasonable depth and width in the concrete targets.
