不同结构形式的雷达天线座预埋件分析与比较

Analysis and Comparison of the Different Structural Forms of Radar Antenna Pedestal Embedded Parts

针对不同结构形式的雷达天线座预埋件运用有限单元法进行了分析、计算。根据实际工况选择体单元建立了三种不同预埋件的有限元模型;给出了预埋件模型计算的边界条件;在有限单元模型上加载边界条件,根据线性理论解算得出计算结果,并且根据计算结果对三种不同的天线座预埋件结构形式进行分析,结合安装过程给出以后预埋件设计的建议。

Finite element method is apphed to design and calculation of the different structural forms of radar antenna pedestal embedded parts in this paper. Finite element model of the embedded parts are built by sohd element chose according to the actual work condition; Boundary conditions is summed up also. With boundary conditions finite element model has obtained its result according to hnearity theory, and analyzed according to the results on three different antenna pedestal embedded parts structure, with reference to the installation process later embedded design recommendations is given.
