摘要

为了研究聚能射流对土壤/混凝土复合目标的侵彻效应，分析土壤/混凝土复合目标在聚能射流侵彻下的响应特性，通过考虑聚能射流侵彻下塑性波在靶板中的传播和衰减，以及在土壤/混凝土界面的反射和透射，分析了反射波和透射波作用下射流对土壤和混凝土的侵彻过程，研究土壤/混凝土复合目标界面效应对聚能射流侵彻的影响，建立了聚能射流侵彻土壤/混凝土复合目标的理论模型。对聚能射流侵彻单一混凝土靶和土壤/混凝土复合靶进行对比试验发现，由于反射波和透射波的影响，聚能射流对土壤/混凝土复合靶的侵彻深度反而低于对单一混凝土靶的侵彻深度。在反射波和透射波的作用下射流的侵彻速度下降，导致了对土壤/混凝土复合靶侵彻深度的降低，试验结果与理论分析一致。

Abstract

In order to study penetration capability by shaped charge jet penetration into soil/concrete target, and characteristic of soil/concrete target under shaped charge penetration, propagation and attenuation of plastic wave, and reflection and transmission at the soil/concrete interface were considered. A theoretic model of shaped charge jet penetration into soil/concrete target was presented by analyzing influence of reflection wave and transmission wave when jet penetration into soil and concrete. The comparison experiments of jet penetration into concrete and soil/concrete target were performed. It is shown that penetration depth of soil/concrete target is lower than that of concrete under jet penetration owing to the influence of reflecting and transmission wave. In the action of reflection wave and transmission wave, the penetration velocity decreases which leading to the penetration depth of soil/concrete target reduce. Theoretic analysis is agreement with experimental result.
