Embodiment Construction

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

[0070] Due to the large number of compression point joints, hinge joints, frame joints, and embedded parts in the string-type semi-rigid substrate, the accuracy of the dimensions and positions of each place is high, and each dimension is linked to each other. Inaccurate assembly of one position will affect the surrounding dimensions. positioning accuracy. Aiming at the above characteristics, the present invention discloses a glued assembly process method of string-tensioned semi-rigid substrate frame, which adopts the method of wrapping carbon wire to control the glued gap of each assembly position, specifically, the wet carbon fiber wire is evenly wound on each The square tube surface of the glued joint ensures that the circumferentia...

Abstract

The invention discloses a glue joint assembly process method for a string-stretching type semi-rigid substrate frame. The glue joint assembly process method comprises the steps that a center frame issubjected to glue joint; reinforcing beams and limiting beams are mounted, and trial assembly is conducted; an outer frame is subjected to glue joint; and angle boxes and angle pieces are subjected toglue joint, and the string-stretching type semi-rigid substrate frame is obtained. According to the glue joint assembly process method, the problems that an existing glue joint process method for thestring-stretching type semi-rigid substrate frame is compact in glue joint construction period, poor in assembly precision, large in assembly stress and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of frame composite material structure manufacturing, and in particular relates to an adhesive bonding assembly process method of a taut string type semi-rigid substrate frame. Background technique [0002] The stringed semi-rigid substrate is a brand-new structural form, mainly to meet the power supply (≥25kw) requirements of the new generation of ultra-large-capacity geostationary orbit satellite platforms, the requirements for weight reduction of the solar wing, and the high deployment stiffness of the solar wing. The string-tensioned semi-rigid substrate is mainly composed of the string-type semi-rigid substrate frame, the string positioning bracket and the Kevlar fiber braided string, and all of them are assembled into one body by adhesive bonding. The stringed semi-rigid substrate frame structure adopts a rectangular tube formed by high modulus carbon fiber / cyanate resin composite material to form the m...
