Problems solved by technology

In the process of aircraft digital assembly, all measurement results need to be transferred to the global coordinate system through the ground reference point (ERS), so the accuracy of the ERS point directly affects the overall accuracy of the aircraft assembly. The high precision of the multi-channel laser tracker Measurement technology, using high-precision edge measurement data, network intersection measurement and combined with adjustment theory to settle coordinates to improve measurement accuracy, but the tooling layout environment of the aircraft component assembly site is complex, many reference points are distributed among them, and the serious line of sight occlusion makes the ground reference point (ERS) the choice is very difficult

Abstract

The invention discloses an aircraft assembly measurement field layout method based on a genetic algorithm, comprising the following steps: establishing an assembly measurement field layout model based on 0-1 planning; solving the assembly measurement field layout model through a genetic algorithm to obtain an optimized layout of the measurement field. The present invention realizes the intelligent optimization of the measurement field layout by establishing a measurement field layout optimization model based on 0-1 planning, and then using a genetic algorithm to solve it, and lays a foundation for high-precision measurement orientation points. The layout optimization model of the measurement field is established by using 0-1 planning, so that the layout problem of the complex measurement field becomes clear, concise and easy to solve; and then the genetic algorithm is used to solve the model, which is efficient and convenient.

Description

Technical field [0001] The present invention belongs to the field of positioning point measurement, and in particular to aircraft assembly measurement field layout method based on genetic algorithm. Background technique [0002] With the development of my country's aviation cause, the accuracy of the new model aircraft is getting higher and higher. During the digital assembly of the aircraft, all measurements need to be transferred to the global coordinate system through the ground reference point (ERS), so the accuracy of the ERS point directly affects the overall accuracy of the aircraft assembly, and the high-precision of multi-channel laser tracker Measurement technology, using high-precision test data, the network payment measurement and combined with the combination theory settlement coordinates to improve the measurement accuracy, but the tooling arrangement of the aircraft component assembly is complex, and many reference points are distributed, and severe sight occasion ...
