Form-Finding Analysis of Mesh Reflector of Large Parabolic Cylindrical Antenna

In this study, a hybrid iteration force density method (HIFDM) was proposed to ensure both tension uniformity and accuracy of an antenna mesh reflector. Based on genetic algorithm (GA), the boundary cable reflector net optimized, which further improved precision The static model large deployable structure established using finite element (FEM), thus, iterative strategy for form-finding proposed, considered influence elastic deformation structure. results showed that HIFDM effective reflector, shape by optimization GA. Finally, it noted will reduce affect reflectors. Due large-scale soft stiffness, had high sensitivity pretension, is important design reasonable pretension accurate
