Constrained Balancing Techniques for Flexible Rotors

Abstract

Several methods for identifying the unbalance causing deflection of a flexible rotating shaft are developed. All methods presented permit the magnitude of the balance weights to be controlled. The formulations may be grouped into categories of either time independent schemes or time dependent schemes. The formulations are also characterized by the type of measure adopted for the identification, e.g., minmax or least squares fits. Numerical results are presented for some of the methods.
