In fluid dynamic bearings operated under mixed lubrication condition, the surface roughness and shape of the sliding surfaces change due to wear in the contact zone, resulting in changes in bearing characteristics over time. In this study, we developed to predict changes in bearing properties over time due to wear. Specifically, a coupled simulation of solid contact analysis considering roughness and shape change due to wear and fluid lubrication analysis based on the solution of the Reynolds equation were conducted. In addition, the effects of roughness and shape change on bearing characteristics in a plane-tilted bearing are discussed, focusing on the instability of the system.
