TLDR
A modal balancing technique may be used for all modes through whose critical speeds the shaft runs, and then an averaging technique can account for the remaining modes.Abstract:
Details are given of a practical technique that has been developed for the balancing of large flexible rotors. The special conditions that arise when such a rotor is borne in bearings from which vibration readings are taken are described. A modal balancing technique may be used for all modes through whose critical speeds the shaft runs, and then an averaging technique can account for the remaining modes.read more

Review: Rotor balancing
TL;DR: This article reviews the literature concerning the balancing of rotors including the origins of various balancing techniques including ones that use influence coefficient, modal, unified, no phase, and no amplitude methods to balance.
Journal ArticleDOI
Balancing of Rotating Machinery
TL;DR: An important form of vibration experienced by rotating machinery in a wide range of applications is that due to inherent unbalance, but emphasis is given to a review of techniques for the high-speed balancing of flexible shafts.

Modal balancing of flexible rotors without test runs: An experimental investigation
TL;DR: In this article, the Gasch and Drechsler method is extended to multibearing rotors with initial shaft bow and the results show that flexible shafts mounted in ball bearings can be balanced with very good results.
Journal ArticleDOI
A theoretical introduction to the development of a unified approach to flexible rotor balancing
TL;DR: In this paper, the authors consider that in practice many of the differences are more apparent rather than real and that the time has arrived for an attempt to reconcile the differences and hopefully to synthesize a method which includes the best features of both methods.

On the Possibility of Balancing Rotating Flexible Shafts
TL;DR: In this paper, it was shown that, provided certain requirements as to the nature of the bearings are met, the approach described by van de Vegte may be unnecessarily complicated, in that only one motorized balancing head need be used, while neither the reference to 'discs' nor the restriction to two bearings may be needed.

The Vibration and Balancing of an Unbalanced Flexible Rotor
TL;DR: In this paper, the motion of a flexible unbalanced rotating shaft is examined and the effects of balancing such a shaft (as a "rigid body") in a conventional low-speed balancing machine are explained.

TL;DR: Methods are suggested for overcoming the difficulty of balancing axially-symmetric flexible shafts and the results of an experimental investigation of these proposals are included.
