Abstract: This paper provides a time transient method for solving coupled lateral and torsional analysis of a flexible rotor–bearing system including gyroscopic effects, nonlinear short journal bearings, nonlinear short squeeze ...

Abstract: Tilting pad journal bearings (TPJBs) provide radial support for rotors in highspeed machinery. Since the tilting pads cannot support a moment about the pivot, selfexcited crosscoupled forces due to fluidstructure interactions ...

Abstract: Gasexpanded lubricants (GELs) are tunable mixtures of synthetic oil and carbon dioxide that enable dynamic control of lubricant viscosity during bearing operation. This control can help reduce bearing power loss and operating ...
