AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively predict the initial imbalance of the combined rotor of an aero-engine, which affects the overall rotor vibration level. Furthermore, there is a lack of sensitivity analysis of the combined balancing process and the design parameters of the balancing tooling.

Method used

By establishing simplified models of the first workpiece, the second workpiece, the first balancing fixture, and the second balancing fixture, the unbalance is estimated separately. Combined with the model of the combined workpiece, the unbalance of the combined workpiece is estimated, providing correction guidance.

Benefits of technology

It enables accurate prediction of the unbalance of assembled workpieces, improves the balance quality of assembled workpieces, and enhances the vibration performance of aero-engines.
