Abstract

The invention discloses a method for determining position coordinates of an aircraft component assembly support station, including weighing, aircraft component segmentation, load function and deflection curve function calculation, and position coordinate search calculation. The optimization method realizes the further optimization and adjustment of the selection of the station coordinates on the basis of the preset station coordinates to ensure the optimal station and avoid excessive deformation of aircraft components; Suggestions on the adjustment of component support positions; and because the present invention uses the search calculation method to search and calculate the optimal position coordinates of each position number, it is guaranteed that each search result can make the aircraft components deform under the position number Therefore, it can ensure that the deformation of aircraft components meets the technical requirements with the minimum number of support stations, and reduce the number of hyperstatic supports as much as possible.

Description

technical field [0001] The invention relates to the field of assembly technology, in particular to a method for determining coordinates of an aircraft component assembly support station. Background technique [0002] The aircraft is usually divided into front fuselage, middle fuselage, rear fuselage, wing, empennage and other parts according to the design and process requirements. These parts are collectively referred to as "aircraft parts"; "Type" assembly, that is, the parts are assembled flat on the frame, and the axis of the parts is parallel to the ground; [0003] Before carrying out the design of the horizontal type frame of the aircraft part, the plan design of the support station of the aircraft part by the horizontal type frame should be carried out according to the structural form and characteristics of the aircraft part. At present, the horizontal type frame support station of the aircraft part is being carried out When designing the position, the way to obtain ...
