Abstract EN
Flexible rotor balancing, in general, relies to a great extent on physical insight into the modal nature of the unbalance response.
The objective of this investigation is to develop a hybrid experimental/analytical technique for balancing high-speed flexible rotors.
The developed technique adopts an approach that combines the finite element modeling, experimental modal analysis, vibration measurements, and mathematical identification.
The modal imbalances are identified and then transformed to the nodal space, in order to determine a set of physical balancing masses at some selected correction planes.
The developed method does not rely on trial runs.
In addition, the method does not require operating the supercritical rotor in a high-speed balancing facility, while accounting for the contribution of higher significant modes.
The developed scheme is applied to a multidisk, multibearing, high-speed flexible rotor, where the interaction between the rotor-bending operating deflections and the forces resulting from the residual unbalance are appreciable.
Some new benchmark solutions and observations are reported.
The applicability, reliability, and challenges that may be encountered in field applications are addressed.
