摘要

在线主动平衡系统因可实时抑制旋转设备运行过程中的不平衡振动,在高端机床和航空发动机等高端装备领域具有重要应用价值。平衡执行器作为主动平衡系统的终端执行机构,其性能参数决定了平衡系统的整体指标。对已有电磁滑环式平衡执行器的轴向励磁方法进行了改进研究,提出了一种基于径向励磁和永磁-电磁联合驱动方法的新型执行器结构,通过建立有限元模型定量分析了执行器的关键性能参数,并最终通过实验验证了上述结构的可行性和有效性。结果表明,径向励磁结构在整周范围内均可驱动配重盘完成自锁和步进动作,结构设计方案可行,且利用永磁-电磁联合驱动可将驱动电压有效降低12.5%,为该类执行器的工业应用提供了技术支撑。

Abstract

An active balancing system can suppress the unbalance vibration of rotating equipment in real time, and has an important application value in the high-end equipment field, such as high-end machine tools and aircraft engines. As a terminal actuator of active balancing system, the performance parameters of the balancing actuator determine the overall index of balancing system. In the paper, the axial excitation method for the existing electromagnetic-ring balancing actuator was improved, a novel actuator structure based on radial excitation method was proposed. The key performance parameters of the actuator were quantitatively analyzed by establishing a finite element model, and the feasibility and effectiveness of the structure were verified by experiments. The results show that the radial excitation structure can drive the counterweight disc to complete self-locking and step-by-step action in the whole cycle. The structural design is feasible, and the drive voltage can be effectively reduced by 12.5% through the permanent magnet-electromagnetism combined driving method, which provides technical support for the industrial application.
