Read the Abstract

The paper discusses the authors’ experience with a turboexpander (TEX) equipped with active magnetic bearings (AMBs) in a natural gas processing facility. The TEX was unable to achieve design performance due to high sub-synchronous vibration since its commissioning. Rotordynamic simulations revealed that the most likely root-cause of the high vibration was the excitation of an unstable rigid body mode of the rotor-bearing system due to high cross-coupled stiffness effects. The paper also discusses the redesign features incorporated into the TEX that resolved the sub-synchronous vibration.
