摘　　要：The on-line active balancing system can suppress the vibration caused by unbalance of rotating equipment in real time,and is of great strategic significance for high-end equipment in machining,aviation and other fields.As the core equipment of the on-line active balancing system,the performance parameters of the active balancing actuator determine the overall performance of the balancing system.The balancing method of the existing mechanical balancing actuator is improved,and a new active balancing actuator structure based on ultrasonic motor is proposed.The stress distribution of the actuator is analyzed by establishing a three-dimensional model of the actuator.The feasibility and effectiveness of the above structure are verified by the experimental research on the grinder.The results show that the active balancing actuator based on ultrasonic motor can drive the counterweight to complete the required self-locking and stepping actions in the whole cycle.The structural design scheme is feasible.At the same time,it also shows that the actuator can suppress the unbalance vibration of the grinder.The active balancing actuator based on ultrasonic motor drive studied in this paper lays a foundation for the industrial application of this kind of actuator in the future.
