title = "Rotor active vibration control via internal magnetic bearings and a concentric inner shaft coupling",
abstract = "A novel topology based on active magnetic bearing coupling for reducing synchronous vibration in rotors at critical speeds is outlined. The topology consists of a hollow rotor with a flexible concentric secondary shaft running along its length. Between the two shafts are one or more actively managed couplings. A design of a test rig to illustrate the effectiveness of the concept is presented, and results of finite element modelling on the rig are provided. It is shown that for the specific topology modelled, peak vibration amplitudes are around an order of magnitude lower than those of a decoupled rotor.",
