Problems solved by technology

Domestic OEMs often use stack optimization methods combined with practical experience to control the coaxiality of the rotor and the initial unbalance level when assembling, but the one-time pass rate of assembly is still low, and the actual effect is not ideal

Abstract

The invention relates to an optimization method for rotor assembly assembling. The optimization method comprises the steps of obtaining all levels of rotor assembling phases with the minimum coaxiality of a rotor assembly through optimization by means of an optimization algorithm; obtaining all levels of rotor assembling phases with the minimum unbalance amount of the rotor assembly through optimization by means of the optimization algorithm; and finding all levels of rotor assembling phases which not only can meet the coaxiality index and but also can meet the unbalance amount index through optimization by means of a comprehensive optimization algorithm of the coaxiality of the rotor assembly and the unbalance amount of the rotor assembly. According to the invention, the rotor coaxialityand the initial unbalance amount can meet the requirements at the same time, and the one-time qualification rate of rotor assembly assembling is improved.

Description

technical field [0001] The invention relates to a method for optimizing the assembly of a rotor assembly. Background technique [0002] The rotor system of large rotating machinery is generally assembled from multiple rotor parts, such as aero-engines, which have large size, significant weight, complex configuration, a large number of precision rotors, and high operating speed. Balance indicators are very demanding. [0003] Poor assembly of the rotor assembly may cause engine vibration, and in severe cases may cause engine failure. Therefore, the control of the structural state and assembly quality of the engine rotor is extremely critical. [0004] At present, the assembly method of the rotor assembly is mainly a stacking optimization method for optimizing the rotor geometric coaxiality target. However, due to the limited processing level of domestic rotor parts, the stacking optimization method developed abroad is "unacceptable". Domestic OEMs often use the combination ...
