摘要/Abstract

摘要： 高速智能装备如何少故障或者无故障长周期运行受到国内外学者的广泛关注，而不平衡振动是其典型故障之一，目前尚缺少有效地在线抑制措施。介绍一种可集成安装在转轴内部的新型压液式不平衡振动自愈调控系统，基于压缩空气驱动平衡液体转移的基本原理，可通过在线调整执行器自身质量分布，实时抑制高速装备的不平衡振动，进而提高其运行安全性和可靠性。定量分析平衡执行器的平衡速度和平衡精度等性能参数，并通过在模拟试验台上验证该系统的有效性。试验结果表明，所述压液式自愈调控系统在多个转速下均可将试验台的不平衡振动有效抑制在0.4 μm以下，振动降幅均在80%以上，最高试验转速达15 600 r/min。为后续高速不平衡振动自愈调控系统的实际工业应用奠定了技术基础。

Abstract: How to make intelligent equipment run in a long period with few faults has attracted extensive attention by scholars at home and abroad,while unbalance vibration is one of its typical faults and still no effective online suppression method. Based on the basic principle of balance liquid transfer driven by compressed air, a novel fault self-recovery regulation system of pneumatic liquid type integrated in the rotating shaft is constructed to restrain the unbalance fault in real time by adjusting the mass distribution of the balancing actuator, which can improve its operation safety and reliability. The performance parameters of balancing actuator, such as balancing speed and balancing precision, are analyzed quantitatively, and the effectiveness of the system is on the simulation test rig. The experimental results show that the system can effectively suppress the unbalance vibration of the test rig at multiple rotational speeds, the vibration reduction is more than 80%, and the maximum experimental speed is 15 600 r/min. It lays a technical foundation for the practical industrial application of the follow-up high-speed unbalance vibration self-recovery regulation system.
