Single-Plane Auto-Balancing of Rigid Rotors
This paper presents an analytical study of single-plane automatic balancing of statically and dynamically unbalanced rigid rotors, considering also the effect of partial unbalance compensation and vibration reduction. We consider a rotor equipped with a selfbalancing device consisting of a circular track with moving balls to compensate for rotor unbalance. The investigations include an analysis...

متن کاملImbalance Estimation for Speed-Varying Rigid Rotors Using Time-Varying Observer
Rigid rotor dynamic model is widely used to model rotating machinery. In this paper, a speed-varying transient rigid rotor model is developed in the state space form. The states of this model are augmented to include imbalance forces and moments. A time-varying observer can then be designed for the augmented system by using canonical transformation. After obtaining an estimation of the imbalanc...
متن کاملAlmost-global tracking for a rigid body with internal rotors
Almost-global orientation trajectory tracking for a rigid body with external actuation has been well studied in the literature, and in the geometric setting as well. The tracking control law relies on the fact that a rigid body is a simple mechanical system (SMS) on the 3−dimensional group of special orthogonal matrices. However, the problem of designing feedback control laws for tracking using...
متن کاملSommerfeld-effect in Automatic Balancing
Automatic balancing devices, comprising several balls in circular tracks, can efficiently compensate rigid rotor unbalance within certain ranges of rotational speed. However, near critical speeds the vibration level can be comparatively high due to the phenomenon, which is similar, but not identical to the well-known Sommerfeld-effect in unbalanced rotors with a limited driving moment. The pres...
