Hydrostatic Thrust Bearing with a Self-Controlled Restrictor Using a Floating Disk. Step Response Characteristics.

Abstract

This paper describes the frequency response of a hydrostatic thrust bearing which can attain very high static stiffness using a new type of self-controlled restictor. Many design parameters affect the frequency-response characteristics of this type of bearing. Here, the influcences of each parameter on the frequency response are theoretically investigated, and the theoretical results are compared with experimental ones in order to confirm the validity of the theoretical predictions. It is found that the hydrostatic thrust bearing with the self-controlled restrictor consistently shows a stable frequency response.
