本文介绍了悬臂转子旋转机械振动的抑制方法。我们提出了一种由橡胶弹簧支撑的转子-轴系统，橡胶弹簧安装在电磁铁的极面上。这是一种混合型设备，其中轴承外壳由橡胶弹簧弹性支撑，并由电磁执行器主动控制。这些执行器由底座和/或滚轮上的位移传感器控制，可以施加电磁力来抑制滚轮的任何振动。在分析中，我们计算了使压路机处振动幅值最小的控制器增益。实验结果与分析结果相吻合，证实了混合式装置是一种非常有效的抑制振动的方法。
This paper describes the suppression of vibration which is generated on rotating machinery with an overhung rotor. We propose a rotor-shaft system supported by rubber springs which are installed on the pole surfaces of the electromagnets. This is a hybrid type equipment in which a bearing housing is supported elastically by rubber springs and controlled actively by electromagnetic actuators. These actuators are controlled by displacement sensors at the pedestal and/or the roller and can apply an electromagnetic force which suppresses any vibration of the roller. In the analysis, we calculate the controller gains which minimized the amplitude of vibration at the roller. In the experiment, the results correspond to the analytical results, and we confirm that the hybrid type equipment is a highly effective method for vibration suppression.
