Investigation on Pivot Rolling Motion Effect on the Behavior of Rocker Back Tilting Pad Journal Bearings

Abstract: The rolling motion of the pads with rocker back (RB) and ball and socket pivots is normally neglected in common software programs for the study of the rotor dynamic behavior of tilting pad journal bearings (TPJB). In other words, the theoretical contact point of the pivot is considered fixed. The aim of this work is to provide a novel way to implement in commercial software the effect of the variation of the circumferential coordinate of the theoretical contact point due to the pad rolling motion in RB TPJB.

“…Their work's novel findings show that the investigated bearings' proper functionality requires a non-uniform bearing clearance and identification of the critical axial force for operation stability. Betti et al [4] dealt with the tilting pad journal bearings, their modeling, and their effect on the dynamical behavior of rotors. Schilling and Liebich [5] conducted experimental research on the influence of a nominal bearing clearance on the lift-off behavior and the load-carrying capacity of gas polymer bearings.…”
