英文摘要:
      Mass imbalance-induced vibration affects the rotating machinery very large, especially the high-speed types. Off-line balancing techniques have been widely developed for rejecting unbalance-induced vibration but do not eliminate unbalanced vibration in the working state. Moreover, multiple start-stops are required in off-line balancing techniques. Therefore, research on an efficient electromagnetically-driven auto-balancer is carried out in the present work, and an internal excitation actuator is designed in this balancer. The electromagnetic characteristics of the two copper coil bobbins in the internal excitation actuator are compared and analyzed. The permanent magnets inside the actuator are simulated and analyzed with different sections of round, rectangular, and elliptical. And the results show that the elliptic type has the largest self-locking force. Finally, the dynamic balance test is performed on a test bench equipped with a designed electromagnetic balancing actuator, and the unbalance vibration is reduced from 130.23μm to 5.98μm.
