摘要(Abstract)：

准确掌握靶后破片的空间分布规律是有效开展聚能装药对装甲目标内部环境毁伤效应评估的先决条件。通过试验和有限元仿真对典型聚能装药侵彻不同倾角靶板产生靶后破片过程进行了研究,结果表明:射流穿透靶板瞬间,大量碎片在靶后形成"椭圆体"破片云,随着靶板倾角增大,靶后破片云朝着靶后法线一侧偏转,其水平截面(与射流轴线垂直的截面)由圆形逐渐变为椭圆,但靶后破片间最大飞行夹角始终保持在90°左右。
To effectively evaluate the damage of internal environment of armored target by shaped charge,grasping the spatial distribution rule of behind armor debris(BAD)accurately was the precondition.With experiment and numerical simulation method,the formation process of BAD of typical shaped charge penetrating target plate under different angles was studied.The results indicated that the jet penetrating the target plate moment,a "ellipsoid" BAD cloud with a large number of fragments was formed behind the target.And with the angle increasing,the BAD cloud deflected to the normal of the target back,the level cross section of the BAD cloud changed from circle into oval,but the maximum emission angle of the BAD always stayed around 90°.
