Abstract
Squeeze-film dampers are often used to improve the stability of high-speed rotating machinery. The introduction of a hydrostatic bearing as an additional damper support can further optimize the loading capacity and damping effects of the support system. This paper investigates the application and limitations of a pressurized deep-pocket hydrostatic damper in a journal bearing-supported rotor system. A typical commercial centrifugal compressor is used as an example for the analysis. Both computer simulations and experimental results indicate that a support system using a journal bearing with offset halves and a hydrostatic damper can provide stable-and low-vibration operation. Data obtained from the same system with tilting-pad bearings are also presented for comparison.
