Abstract

The invention provides a compensating method for an irregular gap in spacecraft structure assembly. The compensating method comprises the following steps of: selecting flexible fiber cloth with a proper thickness according to the dimension of a gap between structures, soaking the fiber cloth into an adhesive or brushing the surface of the fiber cloth, adhering the fiber cloth with the adhesive tothe surface of a connecting surface, regulating a mounting structure to needed precision and fastening the mounting structure; and pressing the flexible fiber cloth with the adhesive into a gap shapethrough fastening force of two connecting structures, extruding out excessive adhesive, wiping off the extruded excessive adhesive, and completely compensating the gap between every two assembly structures by a compensating and adhering layer after the adhesive is cured. The compensating method provided by the invention adopts the flexible fiber cloth and the adhesive as a compensating layer, andthe compensating layer sufficiently utilizes softness of the fiber cloth and liquidity of the adhesive, so that complete filling of a complex gap of an irregular interface is realized; and moreover, relatively high strength and relatively high rigidity are achieved.

Description

technical field [0001] The invention relates to a method for compensating assembly gaps of spacecraft structures. Background technique [0002] Some parts of the spacecraft are complex in configuration or due to the use of composite materials to process the surface with low precision, and the matching precision during assembly is low, which is generally solved by product surface trimming or adding gaskets. When the gap is irregular, the surface of the product or the gasket needs to be trimmed several times for trial assembly, the operation is complicated, the efficiency is low, and the gap cannot be completely eliminated. The existence of gaps can easily lead to uneven force, cause stress concentration, and affect the performance and reliability of the product. Contents of the invention [0003] In order to realize the seamless filling of irregular interfaces and complex gaps, the present invention provides a compensation method for irregular gaps in the assembly of space...
