Finite Element Analysis of Radar Antenna Structure Based on ANSYS

This article has studied the basic principle and implemented method of the radar antenna structure′s finite element analysis,established the finite element model of antenna structure in the great general FEM software ANSYS,process strong analysis,intensity analysis and buckling analysis through the work load and checkout load,implement the guidance on design,produce and decision of antenna structure.The results indicate that the use of finite element method in antenna design is able to proofread technique target,and regard as foundation of lighten weight and achieve optimizing structure.This method can be used as an important reference for further reliability、manipulation and flexibility of radar antenna.
