Analysis of the transient response of an automatic dynamic balancer for eccentric rotors

Author(s) : Green, K , Champneys, AR , Friswell, MI
Description : This paper investigates the transient response of a dynamical system modelling an automatic dynamic balancing mechanism for eccentric rotors. By using recently developed computational techniques, pseudospectra of the linearisation of the system about an equilibrium are computed. This approach allows...

A consideration of support asymmetry in an automatic ball balancing system

Author(s) : Rodrigues, DJ , Champneys, AR , Friswell, MI , Wilson, RE
Description : We present an analysis of a two-plane automatic balancing device for rigid rotors. Ball bearings, which are free to travel around a race, are used to eliminate imbalance due to shaft eccentricity or misalignment. Here we consider the effect that asymmetries such as support anisotropy have on the aut...

Device asymmetries and the effect of the rotor run-up in a two-plane automatic ball balancing system

Author(s) : Rodrigues, DJ , Champneys, AR , Friswell, MI , Wilson, RE
Description : We present a numerical investigation of a two-plane automatic ball balancer (ABB) for rotating machinery. This device consists of a pair of circular races that are set perpendicular to the shaft in two distinct planes. Within each race are a series of balancing balls which move to compensate any mas...

Automatic balancing of a rigid rotor with misaligned shaft

Author(s) : Rodrigues, DJ , Champneys, AR , Friswell, MI , Wilson, RE
Description : We present a nonlinear analysis of the dynamics of an automatic ball balancer (ABB) for rotors which are both eccentric and misaligned. The ABB consists of two or more ball bearings which are free to travel around a circular race at a fixed distance from the shaft. The balls, after a transient respo...

Experimental investigation of a single-plane automatic balancing mechanism for a rigid rotor

Author(s) : Rodrigues, DJ , Champneys, AR , Friswell, MI , Wilson, RE
Description : We present an experimental investigation of a single-plane automatic balancer that is fitted to a rigid rotor. Two balls, which are free to travel around a circular race, are used to compensate for the mass imbalance in the plane of the device. The experimental rig possesses both cylindrical and con...

Two-plane automatic balancing : a symmetry breaking analysis

Author(s) : Rodrigues, DJ , Champneys, AR , Friswell, MI , Wilson, RE
Description : We present an analysis of a two-plane automatic balancing device for rotating machinery. The mechanism consists of a pair of races that contain balancing balls which move to eliminate imbalance due to rotor eccentricity or principal axis misalignment. A model is developed that includes the effect of...

The stability of automatic ball balancers

Author(s) : Green, K , Friswell, MI , Champneys, AR , Lieven, NAJ
Description : One realisation of an automatic balancer uses two or more balls that are free to travel in a race, filled with a viscous fluid, at a fixed distance from the shaft centre. The objective is for the balls to position themselves so that they counteract any residual unbalance. The fact that no external f...

Investigation of a multi-ball, automatic dynamic balancing mechanism for eccentric rotors

Author(s) : Green, K , Champneys, AR , Friswell, MI , Munoz, AM
Description : This paper concerns an analytical and experimental investigation into the dynamics of an automatic dynamic balancer (ADB) designed to quench vibration in eccentric rotors. This fundamentally nonlinear device incorporates several balancing masses that are free to rotate in a circumferentially mounted...

Automatic two-plane balancing for rigid rotors

Author(s) : Rodrigues, DJ , Champneys, AR , Friswell, MI , Wilson, RE
Description : We present an analysis of a two-plane automatic balancing device for rigid rotors. Ball bearings, which are free to travel around a race, are used to eliminate imbalance due to shaft eccentricity or misalignment. The rotating frame is used to derive autonomous equations of motion and the symmetry br...
