Abstract

The invention discloses an aero-engine multi-shaft rotor assembling method and device based on genetic algorithm optimization, and belongs to the mechanical assembling technology. A measurement method and device determine a rotation standard based on a pneumatic-magnetic combined rotation shaft system; angle positioning of a rotary platform is determined according to an inductosyn, a radial error of a rotor radial assembling surface and an inclination error of an axial assembling surface are extracted based on a four-measurement-head measuring device, and the influence weight of each rotor on the coaxiality of all the assembled rotors is obtained; all the rotors needing by assembly are measured respectively, and the influence weight of each rotor on the coaxiality of all the assembled rotors is obtained; vector optimization is carried out on the weights of all the rotors, and the assembling angle of each rotor is obtained. The aero-engine multi-shaft rotor assembling method and device based on genetic algorithm optimization can effectively resolve the problem that the coaxiality is low after the rotors of an aero-engine are assembled, and has the advantages that the coaxiality is high after the rotors are assembled, vibration is reduced, installation is easy, flexibility is high, and the performance of the aero-engine is improved.

Description

technical field [0001] The invention belongs to mechanical assembly technology, and mainly relates to an aeroengine multi-axis rotor assembly method and device based on genetic algorithm optimization. Background technique [0002] Aeroengine assembly is the last link in the manufacturing process of aeroengine, and it is also one of the most important manufacturing links. Under the conditions of the existing aero-engine design scheme and processing technology level, the quality of assembly and work efficiency have an important impact on the quality, performance and production efficiency of the engine. Therefore, in the assembly process, the coaxiality of the installed rotor should be improved as much as possible, so as to reduce the vibration of the aero-engine and improve the performance of the aero-engine. However, in actual production, the assembly of aero-engines is completely manual assembly. The level of assembly accuracy and stability depends entirely on the experienc...
