PRELIMINARY INVESTIGATION OF THE DYNAMIC FORCE RESPONSE COEFFICIENTS FOR SQUEEZE FILM BEARING DAMPERS

摘要

An experimental study of the hydrodynamic force response of a squeeze film bearing damper with end seals was carried out. Measurements of the pressure distribution about a journal constrained to more in a circular orbit were made for the journal orbit centered in the annular clearance and offset from the center of the annular clearance. The effects of cyclic flow in a radial inlet were studied for the case of the journal orbit centered in the annular clearance.
