radar cover meaning in English

雷达探测范围

This paper firstly presents the impact basic theories and the applying method for the general engineering fem software system - ansys , then the preliminary numerical simulation has been conducted in the mechanical process of the laminated composite plates subjecting to the impacting loads , the higher - velocity hit between the composite shells and the metal structures , the bird - impact radar cover experiment is also included . changes of the mechanical values in subjecting to different impact loads are also analyzed
而后通过对复合材料结构层合板遭受冲击载荷作用、球壳与金属板的高速撞击，以及雷达罩鸟撞实验等力学过程进行了初步数值模拟，分析了主要的力学参数量在承受不同冲击变量时的变化，并为部分理论计算找出了相应的实验依据。
