- 摘要：
- A new online balancing device of liquid injection and discharge type grinding wheel was introduced to reduce vibration caused by unbalance of grinding wheel. A new control strategy including initial balance process and phase liquid injection control one was proposed. In initial balance process, dynamic balance calculation was performed according to the system's initial value, and some liquid was injected into the balancing device to rapidly reduce unbalance to a very small value. In phase liquid injection control process, a target vibration value was set up, phase information of grinding wheel's unbalance was used to choose the corresponding injection chamber, and the electromagnetic valve was controlled using a fuzzy-PID controller to do micro-injection many times, and make unbalance value keep a very low level. Grinding wheel dynamic balance test results showed that the vibration caused by grinding wheel unbalance can be reduced by 88% at 2 700 r/min, the feasibility and effectiveness of the proposed strategy is verified.
