Abstract
Wind Loads are one of the main loads causing the instability of the ground-based radome. Due to the existence of joints and riveting solid and other non-integer defects, traditional mosaic structure of the radome affects the radome strength, stiffness and electromagnetic properties. Based on the research results of buckling behavior of CFRP meshed shell radome, the overall stressed-skin structure radome is further proposed. In order to study the deformation and stress performance under WL and to use the method of theoretical analysis and experiment simulation, ANSYS and MATLAB are used to analyze the braided angle of 90° and 60° of stress, strain performance and wind pressure of the radome, the turbulence law of wind speed under the condition of wind angle of 45° from Grade 1, 3 to 17 of wind loads. The results show that stress and strain of the two-kind radomes change as WL change and the change rate is close. The largest difference of wind pressure and wind speed between the two kinds of radomes is about 11.54%, which can provide reference for the design of wind load stability of the structure-function integral radome in actual engineering.
