Embodiment Construction

[0030] The invention proposes a metal mesh laying method for a frame-type expandable reflector. The specific implementation process is divided into four steps. The design surface of the metal mesh is offset by a certain distance; the metal mesh anti-hook hanging piece is installed; the metal mesh passes through the mesh joint and the mesh wire. Connection is made; the metal mesh is sewn with the pressing wire.

[0031] The premise of laying the metal mesh of the present invention is that the truss of the frame type expandable launcher is assembled, such as Figure 5 As shown, that is, the reflector folding rod has been installed on the faceplate, and it has the conditions and status of metal mesh laying. The implementation process of each part is introduced in detail below.

[0032] The first step is to offset the profile of the assembled frame-type deployable launcher along the normal direction of the faceplate to form an offset design profile; as attached Figure 6 As show...

Abstract

The invention discloses a framework type expandable reflector metal net paving method which comprises the steps that (1) an assembled framework type expandable reflector profile is subjected to offset in the disc chuck normal direction, and an offset design profile is formed; (2) a net face hooking-preventing protecting piece is arranged, the net face hooking-preventing protecting piece is of a circular disc structure with a center circular hole, the center circular hole penetrates through a net pressing connector, the net face hooking-preventing protecting piece is placed between the net pressing connector and a disc chuck, and the net pressing connector is connected with the disc chuck; (3) a metal net is arranged on a reflector truss in a paving mode, pretension is exerted, a net pressing piece is placed on the net pressing connector and the metal net, the net pressing piece, the metal net and the net pressing connector are connected to the disc chuck through net pressing screws, and at the time, the net pressing screws cannot be completely arranged in a fastening mode; and (4) a net pressing wire is arranged in a folding rod direction of a reflector in a paving mode, the net pressing wire is wound on the net pressing screws, then the net pressing screws and the disc chuck are arranged in a fastening mode, and the metal net and the net pressing wire are sewn together.

Description

technical field [0001] The invention relates to a laying method of a frame-type expandable reflector metal net, which belongs to the technical field of satellite antennas. Background technique [0002] The frame-type deployable reflector has been applied to many civil and military antennas in my country at present, and the metal mesh laying method involved in the present invention has been verified by in-orbit flight. [0003] The frame reflector is composed of a truss and a metal mesh. The truss is the main body of the reflector structure, which realizes the function of retracting and unfolding the reflector and structural support. The metal mesh is the carrier of the shape of the reflector to realize the function of microwave reflection. [0004] The reflector truss is composed of several tetrahedral units, and the principle of gathering and unfolding the tetrahedral units is as follows: figure 1 As shown, each tetrahedron unit is composed of 3 webs, 3 synchronous folding...
