Pointing behavior of perimeter truss deployable antenna with a laminated reflector

Abstract

Perimeter Truss Deployable Antenna reflector is made of laminated circular plates. The laminated plate would be deformed when it undergoes a large angle rotational motion, and a complex geometric nonlinearity problem would be caused by the coupling effect between the elastic deformation and a large angle rotational motion. According to such reasons, a model of laminated plate which is undergoing a large angle rotational motion based on the high-order shear deformation theory was built. At the same time, we also consider laminated structural parameters and constitutive relations of the plate. And the coupling relation between elastic deformation was analyzed and a large angle rotational motion. Moreover, we derive the rigidflexible coupling dynamics equation using Hamilton variational principle. Furthermore, the necessity of dynamic modeling considering the laminated structure was verified by the numerical simulation.
