An Analysis of Dynamic Characteristics of Tilting Pad Thrust Bearings
틸팅 패드 추력베어링의 동특성 해석
Abstract
In this paper the linearzed stiffness and damping coefficients of tilting pad thrust bearing are calculated by the perturbation method. The coefficients are obtained for a wide range of pivot positions. The effects of exciting frequency and pad mass on stiffness and damping coefficients are investigated. Critical frequencies due to the tilting motions of the pad are presented and are shown to be strongly influenced by the pivot position and pad mass.
