摘要：

This work proposes a novel hybrid gas-magnetic bearing (HGMB) which has single bearing structure. The gas bearing and the active magnetic bearing (AMB) share the same airgap, and the closed magnetic poles are taken as the bushing of the gas bearing. Controllable electromagnetic forces are applied to adjust system dynamic characteristics. Numerical results demonstrate better rotating accuracy, suppressed sub-synchronous vibration, lower energy consumption compared with rigid gas bearings and AMB, and less air friction losses than conventional HGMBs, indicating the suitability of the proposed bearing for cryogenic turbomachinery.
