| The shape-state for the Hoop Truss Deployable Antenna of Mesh Reflector is mainly introduced in this text. The cable net structure, which uses a triangulate cable network to approximate the symmetry reflecting surface and not symmetry reflecting surface under conditions of higher surface accuracy, is firstly generated, which is including the approximated paraboloid with a spherical surface, the segment number for main cable, the coordinate for the interior nodes, and the coordinate for the verge node by considering the verge condition.Shape-state for the cable structure with the triangle cable networks is introduced. The surface accuracy of the cable nets is chosen as objective function, the pre-tension forces in cables as design variables, and the relaxing area, strength and the adequate prestress distributions as constraint conditions, an optimization method to the shape-state is proposed based on the genetic algorithm and finite element analysis, which turns the shape-state of the cable nets into a constrained minimization problem. At last, optimization example of the cable structure is given.Three kinds of cable structure with triangle cable networks are used in the Hoop Truss Deployable Antenna of Mesh Reflector. A shape-state for the whole antenna structure is generated by considering the influence for the cable structure with hoop truss. A optimization example for the shape-state is given.At last, the shape-state software for the Hoop Truss Deployable Antenna of Mesh Reflector is generated. The necessary for the shape-state software is simply introduced. The function of the software and the working flow of the software are introduced. Finally, the software interface design of the shape-state module for the Hoop Truss Deployable Antenna of Mesh Reflector is given. |
