靶后破片是造成装甲内部环境二次毁伤的主要媒介 ,准确掌握其在靶后一定距离和面积上的散布规律具有重要意义.通过X光试验和有限元数值模拟对靶后破片云形态特征进行了研究 ,建立了破片速度散布的数学模型 ,并通过后效铝板获得了破片的散布情况 ,得到了不同厚度靶板下破片速度、破片数量等特征参数随飞散角的变化规律 ,为聚能装药毁伤效应评估提供参考.

The behind armor debris(BAD) was the main medium for the secondary damage to the inter-nal environment of armored vehicle .It was quite significant to accurately grasp the dispersion law of debris in a certain distance and area behind the target .Through X-ray test and finite element numerical simula-tion ,the shape of BAD cloud were studied and the mathematical model of the debris velocity distribution was established . Moreover , the debris dispersion situation was obtained by the aftereffect aluminium plate .The law of characteristic parameters such as velocity and quantity of debris changing with scattering angle under different thickness targets were obtained .It provided a reference for the damage effect assess-ment of shaped charge .
