Abstract: The results of numerous investigators have shown the importance of inlet swirl on the calculated dynamic stiffness and stability of labyrinth seals. These results have not included any calculation ...

Abstract: A total understanding of rotating machinery vibration analysis requires evaluation of critical speed placement, forced response sensitivity to imbalance, linear onset of instability prediction and ...

Abstract: Correction to the definition of the imbalance mass required to correct a disk skew as reported on page 459. The equation was stated correctly, the explanation of the term Uoz was in error. ...

Abstract: The active magnetic bearing (AMB) is a relatively new technology which has many advantages compared with conventional bearing design. In an AMB system, the rolling-element back-up bearings are ...

Abstract: A rotor-hydrodynamic bearing system having external flexible damped bearing supports is more complicated than that discussed in Part 1 but it can provide a means to improve the stability of ...

Abstract: The instability of rotor-hydrodynamic bearing systems has been a major concern in high-speed rotating machine design. The threshold speed is usually considered to be a barrier that cannot be ...

Abstract: The use of liquid ring type oil seals in centrifugal compressors was essential for high pressure applications dating back to the early 1960’s. The analysis of high pressure oil seals was first ...

Abstract: Labyrinth seals are used in various kinds of turbo machines to reduce internal leakage flow. The working fluid, or the gas passing through the rotor shaft labyrinth seals, often generates ...

Abstract: The traditional method for bearing and damper analysis usually involves a development of rather complicated numerical calculation programs that may just focus on a simplified and specific physical ...
