Embodiment Construction

[0069] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments disclosed in the present invention will be described in further detail below with reference to the accompanying drawings.

[0070] Due to the large number of compression point joints, hinge joints, frame joints, and embedded parts in the stretched semi-rigid substrate, the dimensional and positional accuracy requirements are high, and the dimensions are linked to each other. Inaccurate assembly at one location will affect the surrounding dimensions. positioning accuracy. In view of the above features, the present invention discloses a method for gluing and assembling a string-tensioned semi-rigid substrate frame. The method of wrapping carbon filaments is used to control the gluing gap of each assembly position. Specifically, the wet carbon filaments are evenly wound on each The surface of the square tube of the glued joint ensures that the circumferenti...

Abstract

The invention discloses a method for gluing and assembling a string-tensioned semi-rigid base plate frame, comprising: gluing a central frame; installing a reinforcing beam and a limit beam for trial assembly; gluing an outer frame; gluing a corner box and a corner sheet to obtain a stretched-string semi-rigid substrate frame. The invention solves the problems of the existing stretched string type semi-rigid substrate frame gluing process method, such as compact gluing period, poor assembly precision, large assembly stress and the like.

Description

technical field [0001] The invention belongs to the technical field of frame composite material structure manufacturing, and in particular relates to a method for gluing and assembling a string stretched semi-rigid base plate frame. Background technique [0002] The stretched-string semi-rigid base plate is a brand-new structural form, which is mainly to meet the power supply (≥25kw) requirements of the new generation of ultra-large-capacity geostationary orbit satellite platforms, the weight reduction requirements of solar wings and the high deployment stiffness requirements of solar wings. The stretched semi-rigid base plate is mainly composed of a stretched semi-rigid base plate frame, a stretched string positioning bracket and a Kevlar fiber woven stretched string, which are all assembled into one by adhesive bonding. The stretched string semi-rigid substrate frame structure uses a rectangular tube formed by a high-modulus carbon fiber / cyanate resin composite material to...
