A dynamic modeling theory for satellite antenna is presented which is subjected to geometric nonlinearity and coupling deformation of flexible reflector undergoing a large overall motion. For the study of the characteristics of the reflector of the multilayer laminated structure, the displacement field description of a point in a three-node shell element is acquired in conjunction with the thickness, transverse bending, lateral bending, and torsional deformations. Therefore, a nonlinear dynamic model of sat...
