Journal ArticleDOI
Active Magnetic Bearings Stiffness and Damping Identification from Frequency Characteristics of Control System
TL;DR: In this paper, the authors used the magnetic bearing as a sine exciter to identify the stiffness and damping of active magnetic bearings (AMBs) and showed that AMBs stiffness and stiffness have a great relationship with the control system and rotating speed.
Journal ArticleDOI
Identification of dynamic parameters of active magnetic bearings in a flexible rotor system considering residual unbalances
TL;DR: In this article, an identification algorithm was proposed to estimate the stiffness and damping parameters for a flexible rotor AMB system in the presence of unknown residual unbalances by using two independent unbalance response data sets.
Journal ArticleDOI
Dynamic responses of rotor drops onto double-decker catcher bearing
Yili Zhu,Chaowu Jin,Longxiang Xu +2 more
TL;DR: In this article, a double-decker catcher bearing (DDCB) is proposed to enhance the active magnetic bearing (AMB) work performance in AMB system. But because of the lower limited speed of SDCB, it cannot withstand the ultra high speed rotation after rotor drop.
Journal ArticleDOI
Modeling and experimental verification of a squeeze mode magnetorheological damper using a novel hysteresis model
TL;DR: The magnetorheological damper can be used to stabilize precision instruments (balances, optical devices, etc.) to eliminate interference from external vibrational noise, due to the magnetic field as discussed by the authors.
Journal ArticleDOI
Active magnetic bearings used as exciters for rolling element bearing outer race defect diagnosis.
TL;DR: The simulation and experimental results show that the characteristic signal of outer race incipient defect is significantly amplified under the electromagnetic force through the AMBs, which is helpful to improve the diagnosis accuracy of rolling element bearing incipient outer race defect.
