A simple synthesis method of automatic balancing for a system of flexible rotors is proposed in this paper. In order to describe the rotating system, transfer functions with complex coefficients are adopted. The influence coefficients method is used for derivation of the control law. The relationshi

โฆ Synopsis
Some possibilities of automatization of flexible rotors balancing with controlled balancing heads are set out in this paper. A computer is proposed to be the controller. With help of modal analysis of the vibrations generated by unbalance forces a relationship between successive positions of the correction masses is determined. Some calculation procedures for control laws governing the shifting of correction masses in Cartesian or polar co-ordinate systems are introduced. A solution is proposed as to the problem of passing through critical speeds.

The theory of flexible rotor balancing developed in recent years is analyzed in this paper. A relation between the modal balancing and the influence coefficient methods, which are the two main techniques of balancing, is established which is a unified expression of both methods. Then the theory and
Dynamic stability and time responses are studied for an automatic ball balancer of a rotor with a flexible shaft. The Stodola-Green rotor model, of which the shaft is flexible, is selected for analysis. This rotor model is able to include the influence of rigid-body rotations due to the shaft flexib
