A method based on experimentally calibrated rotor model is proposed in this work for unbalance identification of flexible rotors without trial runs.
Influence coefficient balancing method especially when applied to flexible rotors is disadvantaged by its low efficiency and lengthy procedure, whilst the proposed method has the advantage of being efficient, applicable to multi-operating spin speeds and do not need trial runs.
An accurate model for the rotor and its supports based on rotordynamics and finite elements analysis combined with experimental modal analysis, is produced to identify the unbalance distribution on the rotor.
To create digital model of the rotor, frequency response functions (FRFs) are determined from excitation and response data, and then modal parameters (natural frequencies and mode shapes) are extracted and compared with experimental analogies.
Unbalance response is measured traditionally on rotor supports, in this work the response measured from rotating disks instead.
The obtained results show that the proposed approach provides an effective alternative in rotor balancing.
Increasing the number of balancing disks on balancing quality is investigated as A method based on experimentally calibrated rotor model is proposed in this work for unbalance identification of flexible rotors without trial runs.
