This paper studies influence of pad-pivot friction on tilting-pad journal bearings numerically. Wygant [1,2] accomplished experimental studies on the rocker back tilting-pad journal bearing and the ball and socket tilting-pad journal bearing. He detected differences between two types and purposed pad-pivot friction as a main cause. But after his studies, there is no additional study. Therefore this paper suggests an analysis method for the pad-pivot friction and evaluates the effects of pad-pivot friction using numerical method.
