Abstract :
The buckling of composite lattice spokes of deployable antenna with a square cross-section under the action of axial compressive load is investigated in this paper. The finite element lattice model of the spoke with a square cross-section is constructed as a structure, consisting of helical and hoop ribs. The impact of varying the length of the lattice shell, the number of ribs and the angles of their orientation on the stiffness of the structure are considered using of the parametric analysis. According to the results of these studies determined that the method of modeling, presented in this paper, can be successfully applied to the solution of design problems.
