The coupling relationship between the configuration state parameters of the interface-connected rotor system has an important impact on the aero-engine vibration. Taking into account the distribution of component center of mass deviation and skewness of the principal axis of inertial along the axial direction, the essence of rotor configuration state quality control was presented to optimize and control the consistency of the “three axes”. So the rotational inertia internal load of the interface was reduced. A virtual assembly prediction model based on measurable geometric and mechanical parameters of rotor components was established. The collaborative optimization of rotor coaxiality, unbalance, and internal load of the interface was achieved. A closed-loop control scheme covering the entire process of manufacturing-assembly-disassembly was developed. Engineering applications demonstrated that the engine test first-pass qualification rate increased by over 15%, while the fluctuation amplitude of the majority of key parameters was reduced by more than 30%.
