A Built-in Force Actuator for Active Unbalanced Vibration Control of Grinding Wheel

Abstract:

Article Preview

To effectively control unbalanced vibration caused by grinding wheel mass unbalance, a new active control strategy for grinding wheel unbalanced vibration is proposed in the paper, the controllable electromagnetic force which is used to suppress vibration in control scheme originates from the principle of a bearingless motor having a radial magnetic force generation. First, induction electric spindle radial control force model and the force model which is exerted on grinding wheel are analyzed. And then, the dynamic model of induction-type flexural electric spindle-grinding wheel is modeled using finite element method. Finally, an active unbalanced vibration control system for electric spindle-grinding wheel is designed and simulated. The results show that the control scheme has significant effect on suppressing the unbalanced vibration of grinding wheel.
