Abstract: Fluid trapped in a hollow, rotating component may lead to subsynchronous vibrations, resulting in high vibration amplitudes. This asynchronous response is observed around 0.55–0.92× after passing through the first critical ...

Abstract: Squeeze film dampers (SFDs) are widely used to reduce vibration levels in rotating equipment. These devices are installed in series with bearings and are subjected to precessional motions with the inner and outer damper ...

Abstract: Subsea production fluid is quite often characterized by the presence of frac sand, which causes wear within the pump, and alters the performance envelop. One of the design parameters critically affecting reliability is the ...
