摘　　要：提出一种双平面液压主动平衡方法对单盘刚性转子的不平衡振动进行在线消除。在分析双平面液压主动平衡原理的基础上,建立了一套带有单圆盘的转子实验台,制定了双平面的2种安装方案。利用有限元法建立了该实验台的转子模型,分析了2种安装方案的平衡效果,并确定了各个平衡方案下的最佳控制方法。在实验台上对2种安装方案的平衡效果进行了实验验证。有限元分析和实验结果均表明,不同的安装方案需要采用的控制方法各不相同,采用最佳控制方法的双平面主动平衡技术可以有效地消除单盘转子的不平衡振动。A dual-plane active hydraulic balancing method was proposed to eliminate the unbalance vibration of a rigid rotor with single disk online. Based on the analysis of the principle of dual-plane active hydraulic balancing, a test rig with a single-disk rotor was set up, and two active balancing schemes were made. Then, by means of the finite element method （FEM）, a model of the test rotor was built to analyze the balancing effects of the two active balancing schemes and determine the best control method under each balancing scheme. Finally, the two active balancing schemes were experimentally investigated on the test rig. Results of FEM analysis and experiments indicate that the best control method that should be adopted is different under different balancing scheme. The dual-plane active hydraulic balancing method using an optimal control method can greatly depress the level of unbalance vibration.
