摘要
基于有限元法建立天线罩体及其支架的有限元数学模型,对某型飞机预警雷达结构的动态特性进行研究。分析了不同边界条件下天线罩静态特性,得出不同载荷作用下天线罩应力分布情况,通过模态分析得到天线罩的动态特性。
The dynamic characteristics of the structure of airborne early warning radar are studied based on finite element mathematical model. The static characteristics of antenna radome under different boundary conditions are analyzed, the distribution of stress of the radome under different load actions is obtained, and the dynamic characteristics of the antenna radome are obtained based on modal analysis.
