Analysis and Experiments on an Electro-Hydraulic Torsional Servo Vibration Damper

抄録

In order to reduce the torsional vibration, usually passive dampers such as Vickers-Sandner damper have been applied. The major limitation of the passive vibration damper is the requirement for the absorber system parameters to be matched to those of the main structure. On the contrary, some types of active vibration dampers have been reported to be capable of effective operation over a wide range of varying conditions. This paper reports the results of an investigation on an electro-hydraulic active torsional vibration damper. The torsional vibration damper is subject to requirements that it rotates together with the total system or the attaching point in the system is sometimes restricted. In such a case, the resonant peak amplitude can be well damper out with the servo controller when the system parameters are chosen appropriately to the total vibration system.
