METHOD AND APPARATUS FOR ENSURING THE DIMENSIONAL CONSTANCY OF MULTISEGMENT PHYSICAL STRUCTURES DURING ASSEMBLY

摘要

The invention relates to a method for ensuring the dimensional constancy of multisegment physical structures, in particular aircraft structures, during assembly, having the following steps: a spatially-fixed three-dimensional coordinate system (90) which encloses the subsequent assembled physical structure is set up; a plurality of segments (31, 32, 33) of the physical structure to be assembled are introduced into the spatially-fixed three-dimensional coordinate system (90) ; the positions of the individual segments (31, 32, 33) and of already assembled groups of segments (31, 32, 33) are recorded repeatedly within the spatially- fixed three-dimensional coordinate system (90) during assembly; and the position of a respective segment (31, 32, 33) or of a respective already assembled group of segments (31, 32, 33) is corrected if a respective record shows that the positions of the respective segment (31, 32, 33) or of the respective already assembled group of segments (31, 32, 33) is outside a tolerance band, which is predetermined in accordance with a desired dimensional constancy, by a respective predetermined nominal value.
