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. The method comprises the following steps: establishing an assembly measurement field layout model based on 0-1 planning; and solving the assembly measurement field layout model through a genetic algorithm to obtain a measurement field optimized layout. The measurement field layout optimization model based on 0-1 planning is established, and then the genetic algorithm is used for solving, so that intelligent optimization of the measurement field layout is realized, and a foundation is laidfor high-precision measurement of orientation points. A measurement field layout optimization model is established by utilizing 0-1 planning, so that a layout problem of a complex measurement field becomes clear and concise in expression and is convenient to solve; and the genetic algorithm is used to solve the model, which is efficient and convenient.

Description

technical field [0001] The invention belongs to the technical field of positioning point measurement, and in particular relates to a layout method of an aircraft assembly measurement field based on a genetic algorithm. Background technique [0002] With the development of my country's aviation industry, the precision requirements for new aircraft are getting higher and higher. 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 referenc...
