Influence of external excitations on ball positioning of an automatic balancer
چکیده انگلیسی


• The magnitude and frequency of an external excitation affect ball positioning.
• The balls could counterbalance the external force by changing the ball positions.
• Rolling friction prevents balls from moving, which deteriorate performance.
• The ball positions are affected by the external force when ωe = ωr.

This study examined the influence of external excitations on ball positioning in an automatic ball balancer (ABB) installed in a rotor system. The authors' previous studies adopted a model that considered the ABB as an autonomous system by neglecting external excitations. We examined how the magnitude, the frequency and even the phase of an external excitation affected ball positioning. Simulations were performed to predict the ball positions under various external forces. Then, we constructed an experimental rig by employing a shaker to apply excitations to the rotor system and the associated ABB to verify the theoretical development. Simulation results indicated that the balancing balls of the ABB could counterbalance the external force by the change of the ball positions. However, it was observed from the experiment that the ball would not be displaced if the external force was applied after the ball had been positioned because the excessive rolling resistance between the ball and the runway prevented the ball from moving to desired positions.
