Structural Analysis Of The Large-scale Radomes

The electrical performance of the antenna is affected by the stiffness, intensity andstability of the radome structure. Hence, the structural analysis of radome is veryconcerned by the designers.Firstly, a variety of domestic and foreign spherical radomes are classified by thestructure in this thesis. Based on this, the principle of various large spherical radomestructure and their advantages and disadvantages are analyzed and explained, whichmakes a necessary preparation for the analysis of large spherical radome.The detailedintroduction is given about the method and principle of its partitioning. The study andanalysis are carried out on its manufacture, installation and forming process.Secondly, a wind load is discredited in Ansys Parameter Design Language (APDL);the basic characters of wind are described and discussed. And the simulation of wind isaccomplished by the wave superposition method in MATLAB software.Finally, the static analysis, dynamic analysis and buckling analysis of the diameter40m radome structure are carried out by using the finite element method and theprocedure for applying wind load automatically, the influence of block on themechanics properties of the radome is explored by the analysis of the diameter9.144mradome.
