Abstract

Active balancing device of grinding wheel is an important part for high-speed grinding machines. A new type of liquid-transfer active balancing device is proposed and a targeted control strategy is provided for the balancing device. In the strategy, amplitude and phase of imbalance are found before the balancing device works. During the process of balancing, the compressed air is injected to a determination target, the amplitude of vibration decreases monotonically and there is no dysregulated phenomenon. Quantitative analysis is done for several control paths and the optimal path is selected. The experiment result demonstrates that the unbalance response is reduced in 15s for three speed conditions and the decrease in amplitude is more than 90%.
