Abstract: The auxiliary bearing is applied to provide mechanical uphold for the rotational dropping rotor when contact event happens due to the active magnetic bearing (AMB) failure emergencies. During the rotor drop process, the ...

Abstract: Active magnetic bearings (AMBs) have been utilized widely to support high-speed rotors. However, in the case of AMB failure, emergencies, or overload conditions, the auxiliary bearing is chosen as the backup protector to ...

Abstract: In geotechnical engineering, fracture fillings or rough fracture surfaces often resist deformation and enhance the equivalent elastic moduli of fractured rock masses. In this study, the normal stiffness and shear stiffness ...
