相控阵雷达是战场上的主要传感器。相控阵天线是相控阵雷达的主要执行单元，它对相控阵雷达的可靠性有很大影响。因此，天线碎片损伤试验很重要。由于相控阵天线的材料不易获取，天线碎片损伤试验难以开展。于是我们针对这一问题进行了研究，并引入量纲分析原理来解决它。首先，构建了碎片损伤天线目标无量纲模型。其次，利用有限元分析软件ANSYS/LS - DYNA对不同材料进行了大量的量纲分析模拟试验。最后，基于量纲试验分析，给出了相同损伤情况下不同天线目标之间的材料等效经验模型。本研究结果为不同材料的目标损伤试验提供了一种可行且有价值的解决方案。
Phased array radar is the main sensor in a battlefield.Phased array antenna is the main execution unit of the phased array radar,and it greatly affects the reliability of the phased array radar. As a result,the fragment damaged antenna test is important.As the materials of phased array antenna are not easy to get,the fragment damaged antenna test is difficult to carry out. Then we present a study on this problem and introduce the principles of dimensional analysis to solve it. Firstly, the fragments damage antenna target dimensionless model is constructed. Secondly,the finite element analysis software ANSYS / LS-DYNA are used to carry out a large number of different materials simulation test for dimensional analysis. Finally,based on dimensional test analysis,the materials equivalent empirical model between different antennas target is presented in the same damage. The results of this study provide a feasible and valuable solution for different materials’ target damaged test.
